Abstract Objectives The intake of the high dose of polyphenols might cause adverse health effects on humans, in such cases, toxicological testing may be required to ensure safe levels of intake. In the present study, acute and subacute oral toxicity studies of polyphenol-rich European cranberrybush (Viburnum opulus L.) (ECB) fruit extract were evaluated to ensure the safe use of this extract. Methods In acute toxicity, freshly prepared ECB extract dissolved in distilled water was administrated to Sprague-Dawley rats by oral gavage at a single dose of 2000 mg/kg and signs of toxicity and mortality was observed. In subacute toxicity, Balb-c mice were administrated orally at 500 (low dose) and 2000 mg/kg (high dose) of ECB extract for 28 days and their mortality, clinical signs and, body weight were recorded on a daily and weekly basis, respectively. At the end of 28 days, while blood samples from each animal were taken for hematological and biochemical analysis, vital organs were taken for histopathological examination. Results In acute toxicity study, ECB extract showed no toxicological signs observed on behavioral change and body weight of rats after 14 days indicating that the lethal dose (LD50) of the ECB fruit extract might be higher than 2000 mg/kg. No death and no abnormal clinical signs were also recorded in subacute toxicity study. However, the increment in body weight of administrated high dose of ECB extract animals were significantly lower than control (P > 0.05). High dose of ECB fruit extract induced the level of in some hematological parameters. Even amylase and lipase values were lower than normal ranges at high dose animals, other biochemical parameters results were not significantly different from the controls. In histopathological examination, the total histopathological scores ECB extract administrated mice at both doses were showed normal histological features in many tissues compared to control. However, administrated with a high dose of ECB extract showed significant changes in kidney, liver, and adipose tissue that were alterations (edema, infiltration, and bleeding) compared to control. Conclusions These findings indicated that polyphenol-rich ECB extract might show a toxic effect at a high dose (2000 mg/kg) and no observed adverse effect level (NOAEL) of ECB extract was 500 mg/kg ECB fruit juice.

Abstract Background Garcinia lanceifolia Roxb. has been used by many ethnic communities of Northeast India to mitigate various disorders like dyspepsia, ulcers, diabetes, etc. However, a robust scientific study on its antidiabetic and antiulcer potential is unavailable till date. The aim of this present study is to scientifically validate if the antidiabetic and antiulcer effects reported by the ethnic tribes of Assam has any scientific value or not. The effects were tested in adult Wistar albino rats using approved animal models for preclinical testing of pharmacological activities. Results The hydroalcoholic extract of the bark of Garcinia lanceifolia Roxb. was prepared and its LD50 was calculated. The LD50 was determined to be greater than 5000 mg/kg body weight. The extract at doses of 250 mg/kg body weight and 500 mg/kg body weight was found to exhibit a very potent dose-dependent antidiabetic activity. The results were backed by a battery of test including analysis of serum levels of blood glucose, lipid profiles, in vivo antioxidant enzymes, and histopathological studies. Evidence of dose-dependent antiulcer activity of the extract was backed by robust scientific data. It was found that HAEGL induced a significant dose-dependent increase in the ulcer index in both alcohol-induced and acetic acid-induced ulcer models, which was evident from the macroscopic observation of the inner lining of the gastric mucosa and the histological evaluation of the extracted stomach. Conclusion The results suggested that the bark of Garcinia lanceifolia (Roxb.) has significant antidiabetic and antiulcer potential. Further studies with respect to the development herbal dosage forms and its safety evaluation are required.

Abstract Objectives Madhulai Manappagu – a well-known sastric and widely prescribed Siddha herbal syrup formulation indicated for treating Veluppu Noi (Anaemia especially Iron deficiency Anaemia) has been in day today practice in Tamil Nadu for a quite longer decades. The syrup is a herbal preparation which has a sweet pleasant odour and a palatable taste, contain the juice of pomegranate (Punica granatum L.) as the main ingredient. Though the formulation is a fruit juice, the safety profile of the syrup is not established and is being marketed without toxicological evaluation. The study is aimed at ascertaining the acute and sub-acute toxicity assessment of Madhulai Manappagu in Wistar Albino rats. Methods The acute and sub-acute (28day repeated oral) toxicity studies were performed as per the guidelines mentioned in the Organization for Economic Cooperation and Development (OECD) 423 (adopted on December 2001) and TG 407 (adopted on October 2008) with slight modifications respectively. For acute toxicity study, three female rats were randomly selected as control; three female rats were randomly selected and were administered a single dose of 5,000 mg/kg body weight per oral route. For sub-acute (28day repeated oral) toxicity studies, three doses of test drug MM of 500 mg/kg/day (low dose), 750 mg/kg/day (intermittent dose) and 1,000 mg/kg/day (high dose) were selected for administration. Both sexes of Wistar Albino rats were randomized into four groups of 10 animals each (five males, five females). Group I was kept as control group. Group II, III and IV served as low, intermittent and high doses of MM respectively. Animals were observed for mortality, morbidity, body weight changes, feed and water intake. Haematology, clinical biochemistry, electrolytes, gross pathology, relative organ weight and histopathological examination were performed. Results In the acute toxicity study, rats showed no toxicological signs on behavior, gross pathology and body weight of rats when treated with a single dose of 5,000 mg/kg body weight per oral route. In the subacute (28 days repeated oral) toxicity study, rats have showed no significant changes on behavior, gross pathology, body weight, and hematological and biochemical parameters when treated with Madhulai Manappagu in three different doses. Conclusions The toxicity studies which include both acute and 28 days repeated (subacute) oral toxicity studies, revealed no observed adverse effect level (NOAEL) of Madhulai Manappagu in animals. Thus the safety of the drug in human usage was ensured.

Abstract Qing Hao Gan Cao (QHGC), a Chinese medicinal formula containing Artemisia annua and Glycyrrhizae Radix et Rhizoma, has been used to treat sunstroke and as an antiviral agent for more than 800 years. It has not previously been subject to a toxicological safety evaluation in acute and subacute (28 days) studies. Therefore, the acute and subacute toxicity of an aqueous extract of QHGC were evaluated in vivo. For the QHGC preparation, the botanical raw materials were crushed into pieces and mixed in the ratio of 10:1 in distilled water for 12 h, then boiling three times for 2 h each time. The three decoctions were mixed and filtered, then spray-dried with hot air at 160°C for 30 min, and stored at room temperature. For the acute toxicity test, 72.0 g/kg of QHGC extract was administered by gavage to male and female mice. Body weight, general observations, and autopsy results were recorded. No mortality or toxicity signs were observed during the studies. For the subacute toxicity test, 4.0, 8.0, or 16.0 g/kg/day of QHGC extract was administered to rats for 28 days. General observations and mortality, body weight, biochemical and hematological parameters, organ weight, and pathological morphology were analyzed. The acute and subacute toxicity studies did not show significant changes in body weight, general observations, hematology and biochemical parameters, organ weight, and liver, spleen, stomach, duodenum, testis, ovary, lung, heart, and kidney histopathological analyses. The consumption of QHGC aqueous extract can be considered safe within the conditions of this study.

Background. Mantidis Ootheca (MO), described as the ootheca of Hierodula patellifera Serville, 1839, Tenodera angustipennis (Saussure, 1869), or Statilia maculate (Thunberg, 1784) in Korean Herbal Pharmacopoeia, is an important herbal material that has been traditionally used for treating several medical conditions including renal failure, spermatorrhea, and pediatric enuresis in Korea. Objective. The present study investigated the potential subacute toxicity of MO water extract during a 2-week repeated oral administration of doses of 0, 50, 150, or 450 mg/kg/day to C57BL/6 male mice by gavage. Methods. The following parameters were examined during the study period: mortality, clinical signs, body weight, hematology, serum biochemistry, gross findings, organ weight, and histopathology. All the mice were euthanized at the end of the treatment period. Results. No treatment-related changes in mortalities, clinical signs, body weight, gross finding, and organ weight change were detected after 14 days of oral MO extract administration. In addition, no meaningful MO extract treatment-related changes were observed in the hematological, serum biochemical, and histopathological parameters compared with the normal control group following treatment with doses of up to 450 mg/kg/day. Conclusion. Based on these findings, we concluded that treatment of mice with the water extract of MO did not result in significant toxicity and, therefore, it could be considered safe for further pharmacological studies.

Ayurvedic and traditional medical practitioners of Sri Lanka use the decoction of the immature inflorescence of Cocos nucifera L. (IC) variety aurantiaca for the treatment of menorrhagia. The progestogenic effect of the ethyl acetate soluble proanthocyanidins (EASPA) of the IC in female rats at a dose of 3.5 mg/kg body weight has been reported. Acute and subacute toxicity studies of EASPA of the IC carried out using female Wistar rats according to Organization for Economic Co-operation and Development (OECD) guidelines 423 and 407, respectively, are reported herein. In the acute toxicity study, a single dose of EASPA (2000 mg/kg body weight) was orally administered to rats, which were monitored for 14 days. In the subacute toxicity study, rats were orally administered with EASPA daily for 28 days at doses of 1.75, 3.5, 7, and 14 mg/kg body weight. No rat in either the acute or subacute toxicity study exhibited mortality or clinical signs of toxicity. Further, these rats did not show any significant change in their mean body weight, food, and water intake, haematological and biochemical parameters as well as in the results of their histopathological examinations compared to those of control group rats. According to results of the acute toxicity, the LD50 of EASPA is estimated to be greater than 2000 mg/kg body weight. Considering the results of the subacute toxicity study, the oral administration of EASPA daily for 28 days was well tolerated up to the dose, 14 mg/kg by rats. These results will be useful in the development of a novel therapeutic agent from EASPA of the IC for the treatment of menorrhagia, which incapacitates a considerable proportion of women worldwide.

Effect Of Treatment

Decabromodiphenyl oxide (DBDPO) is a highly effective flame retardant that is primarily used in electrical and electronic equipment with a secondary, but important, application in upholstery textiles. DBDPO, the second largest volume brominated flame retardant in use today, has undergone a wide range of toxicology tests in mammalian species with the results indicating a no-adverse-effect level of ∼1000 mg/kg/day in oral repeated-dose studies. An oral prenatal developmental toxicity study of the commercial DBDPO product (97% purity) was performed under current EPA OPPTS and OECD guidelines. Female Sprague-Dawley rats (25 mated females/group) received 0, 100, 300 or 1000 mg DBPDO/kg/day via gavage in corn oil during gestation days 0 through 19. All females survived until scheduled sacrifice. No clinical signs of toxicity were observed. Pregnancy rates in the control and treated groups ranged from 96% to 100% and provided 23 or more litters in each group for evaluation on gestation day 20. No effect of treatment was seen in maternal gestational parameters (body weight, body weight gain, and food consumption), uterine implantation data, liver weight, or necropsy findings. Likewise, no effect of treatment was seen in fetal body weights, fetal sex distribution, or during the fetal external, visceral, or skeletal examinations. The NOEL (noobservable-effect level) for maternal and developmental toxicity was 1000 mg DBPDO/kg/day, the highest dose level administered on gestation days 0 to 19.

DespiteEuphorbia hirtaL. ethnomedicinal benefits, very few studies have described the potential toxicity. The aim of the present study was to evaluate thein vivotoxicity of methanolic extracts ofE. hirta. The acute and subchronic oral toxicity ofE. hirtawas evaluated in Sprague Dawley rats. The extract at a single dose of 5000 mg/kg did not produce treatment related signs of toxicity or mortality in any of the animals tested during the 14-day observation period. Therefore, the LD 50 of this plant was estimated to be more than 5000 mg/kg. In the repeated dose 90-day oral toxicity study, the administration of 50 mg/kg, 250 mg/kg, and 1000 mg/kg/day ofE. hirtaextract per body weight revealed no significant difference (P>0.05) in food and water consumptions, body weight change, haematological and biochemical parameters, relative organ weights, and gross findings compared to the control group. Macropathology and histopathology examinations of all organs including the liver did not reveal morphological alteration. Analyses of these results with the information of signs, behaviour, and health monitoring could lead to the conclusion that the long-term oral administration ofE. hirtaextract for 90 days does not cause sub-chronic toxicity.

Thirty Wistar albino rats of both sex, 1-1.25 months old (average body weight 250 – 300gm) were used. Animals were randomly divided into three groups. 1st group (acute group) n=10 given 0.5 ml. contain 500 mg/kg/body weight NaF, as single toxic dose via stomach tube. 2nd group (chronic group) n=10 given 0.5 ml. contain 150 mg/kg/body weight NaF via stomach tube daily for 60 days. 3rd group (control group) n=10 given 0.5 ml. physiological saline via a stomach tube. Clinical signs were reported during the course of the study, and then sacrificed after 3 and 7 days in 1st group, and 30 and 60 days in the 2nd group, then post-mortem examination was done, and any gross lesions were reported. Blood collected was done for biochemical examination (T3, T4, and TSH.) using special biochemical kits. Pieces of thyroid were taken, fixed in 10% formalin for 72 hours, and then all the specimens were processed and the histopathological changes were observed under light microscope. The pathological results showed hemorrhage appear in the capsular region of the thyroid gland with vacuolation in the cytoplasm of cell of a colloid with neutrophils infiltration in the lumen, as well as edema with fume cytoplasm and marked vacuolation of the cytoplasm of a colloid cell, also granulomatous lesion seated in gland parenchyma. That causes alteration of biochemical test T3, T4 and TSH in acute and chronic toxic doses.

Accumulating evidences have reinforced the use of medicinal plants in the treatment of various ailments as a result of negative side effects associated with conventional drugs. Plant components such as phenols and flavonoids with antioxidant potential have confirmed protective roles against oxidative stress-induced degenerative diseases like diabetes mellitus (DM). The current study was carried out to investigate the effect of seed pod ethanol extract from Copaifera salikounda (SPEECS) in alloxan-induced diabetic rats. SPEECS was obtained by maceration of seed pod powder in absolute ethanol for 72 h, filtered, concentrated and dried in-vacuo. Gas chromatography-mass spectrometry (GC–MS) technique was used to quantitatively elucidate the chemical constituents of SPEECS. Twenty-four male albino rats were randomly allocated into four groups (n=6): normal control, DM control, DM + 200 mg/kg SPEECS and DM + 400 mg/kg SPEECS groups. DM was induced in the Wistar albino rats through intraperitoneal injection of 200 mg/kg body weight of alloxan. After 14 days of treatment, the body weight changes and the fasting blood glucose level were determined in the different groups. Also, serum biochemical parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), albumin (ALB), total protein (TP), malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) were estimated. The GC-MS results confirm nine bioactive compounds with 9-octadecenoic acid (55.75%) being most abundant. SPEECS (200 and 400 mg/kg) administration significantly (P 0.05) caused gain in weight, decreased fasting blood glucose and reversed the elevated liver function enzymes (ALT, AST, ALP) while total TP and ALB were markedly elevated relative to DM control group. Furthermore, SPEECS attenuated the activities of SOD and CAT while the level of MDA was significantly (P 0.05) decreased in dose dependent manner in comparison to the DM control. This study indicated that SPEECS can alleviate hyperglyceamia of DM. Key words: Copaifera salikounda; oxidative stress; medicinal plants; diabetes mellitus; phytochemicals; orthodox ANTIDIABETIČNI UČINEK EKSTRAKTA ETANOLA Copaifera salikounda (HECKEL) NA SLADKORNO BOLEZEN, SPROŽENO Z ALLOXAN-om, PRI PODGANAHIzvleček: Obstaja vedno več dokazov, ki poudarjajo uporabnost zdravilnih rastlin pri zdravljenju različnih bolezni, tudi zaradi različnih negativnih stranskih učinkov, povezanih s konvencionalnimi zdravili. Rastlinske sestavine kot so fenoli in flavonoidi z antioksidativnim potencialom, imajo po nekaterih raziskavah zaščitno vlogo pred degenerativnimi boleznimi, ki jih povzroča oksidativni stres, kot je sladkorna bolezen diabetes mellitus (DM). Študija je bila izvedena z namenom raziskovanja učinka etanolnega semenskega ekstrakta iz rastline Copaifera salikounda (SPEECS) pri podganah s sladkorno boleznijo, ki jo je povzročil alloxan. SPEECS je bil pridobljen z maceracijo praška semen v prahu v absolutnem etanolu 72 ur ter nadaljnjo filtracijo, koncentracijo in sušenjem v vakuumu. Za kvantitativno ugotavljanje kemijskih sestavin SPEECS je bila uporabljena tehnika plinske kromatografije in masne spektrometrije (GC-MS). Štiriindvajset samcev podgan Wistar je bilo naključno razporejenih v štiri skupine (n=6): normalna kontrola, kontrola DM, DM + 200 mg/kg SPEECS in DM + 400 mg/kg SPEECS. DM je bil pri podganah sprožen z intraperitonealno injekcijo 200 mg/kg telesne mase alloxana. Po 14 dneh zdravljenja so bile pri različnih skupinah določene spremembe telesne teže in nivo glukoze v krvi (na tešče). Poleg tega so avtorji raziskave izmerili še nekatere serumske biokemične parametre kot so ravni alaninske aminotransferaze (ALT), aspartatne aminotransferaze (AST), alkalne fosfataze (ALP), albumina (ALB), skupnih proteinov (TP), malondialdehida (MDA), superoksiddismutaze (SOD) in katalaze (CAT). Rezultati GC-MS so v izvlečku SPEECS pokazali devet bioaktivnih spojin, v katerih je največ 9-oktadecenojske kisline (55,75%). SPEECS (200 in 400 mg/kg) je povzročil znatno (P 0,05) povečanje telesne mase, znižanje glukoze v krvi na tešče in znižal raven encimov pokazateljev jetrne funkcije (ALT, AST, ALP), medtem ko je bila raven TP in ALB pri podganah, ki so prejemale SPEECS izrazito povišana v primerjavi z DM kontrolno skupino. Zdravljenje s  SPEECS je tudi oslabilo aktivnosti SOD in CAT, medtem ko se je raven MDA znatno zmanjšala (P 0,05) v primerjavi s kontrolno skupino DM. Ta študija je pokazala, da lahko SPEECS ublaži hiperglikemijo pri sladkorni bolezni pri podganah.Ključne besede: Copaifera salikounda; oksidativni stres; zdravilne rastline; sladkorna bolezen; fitokemikalije; ortodoksni
