Terfezia Claveryi

Brown truffle (Terfezia claveryi) is a wild fungi species collected and consumed by humans in Iraq, especially during the raining season, from February to April. However, the toxicological effects of this fungus have not been studied in humans. This study tested the subacute toxicity of brown truffle’s methanolic extract on a rat model. Daily oral doses of 200, 400, and 800 mg/kg were administered to adult Sprague-Dawley rat groups of both sexes for 14 days. There were no behavioral changes, no alterations in body weight, organ weight, and body weight gain (p>0.05) in the treated rats, compared to the untreated control group. The hematological and serum biochemical parameters did not show significant (p>0.05) differences from the control. Microscopic examinations of the brain, lungs, liver, spleen, kidney, and heart tissues revealed no pathological lesions in treated rats’ organs. These results imply that the administration of methanolic extract of T. claveryi to rats does not result in observable toxicity

The prevalence of infertility due to industrial, environmental and pharmaceutical toxins induced by lead in Nigeria and in developing countries is alarming. The use of medicinal plants as fertility enhancer in human is now in the increase because of the shifting of attention from synthetic drugs to natural plants. Thus, this study investigated the effect of methanolic extract of Telfairia occidentalis on (Pb) lead-induced testicular damage in adult male Sprague-Dawley rats. Twenty-four (24) Sprague dawley (SD) rats with average weight of 130g were randomly divided into four groups of six animals each. Group A served as the control group administered normal saline. Group B received 75mg/kg body weight of lead (Pb) as Lead nitrate only. Group C received 75mg/kg body weight of lead (Pb) and 300mg/kg body weight of methanolic extract of Telfairia Occidentalis, while Group D receive 300mg/kg body weight of methanolic extract of Telfairia Occidentalis only. Administration was via oral canula and the animals were sacrificed on 15th day. Blood samples were obtained via the left ocular sinus for haematological and hormonal studies while the testes and epididymis were removed and fixed in Bouin’s fluid for histological analysis. Administration of Telfairia Occidentalis improves testicular testosterone and PCV levels and also restored the histoarchitecture of the testes in SD rats. It is therefore suggested that the antioxidant potential of this wonder plant may have beneficial effects in treating male factor infertility as shown in this present study.Keywords: Male infertility, Telfairia occidentalis, Lead (Pb), Antioxidants

Purpose Innovative health-promoting approaches of the era have verified phytoceutics as one of the prime therapeutic tools to alleviate numerous health-related ailments. The purpose of this paper is to probe the nutraceutic potential of ginger flowers and leaves against hyperglycemia. Design/methodology/approach The aqueous extracts of ginger flowers and leaves were observed on Sprague Dawley rats for 8 weeks. Two parallel studies were carried out based on dietary regimes: control and hyperglycemic diets. At the end of the experimental modus, the overnight fed rats were killed to determine the concentration of glucose and insulin in serum. The insulin resistance and insulin secretions were also calculated by formulae by considering fasting glucose and fasting insulin concentrations. Furthermore, the feed and drink intakes, body weight gain and hematological analysis were also carried out. Findings In streptozotocin-induced hyperglycemic rats, the ginger flowers extract depicted 5.62% reduction; however, ginger leaves extract reduced the glucose concentration up to 7.11% (p = 0.001). Similarly, ginger flowers extract uplifted the insulin concentration up to 3.07%, while, by ginger leaves extract, the insulin value increased to 4.11% (p = 0.002). For the insulin resistance, the ginger flower showed 5.32% decrease; however, the insulin resistance was reduced to 6.48% by ginger leaves (p = 0.014). Moreover, the insulin secretion increased to 18.9% by flower extract and 21.8% by ginger leave extract (p = 0.001). The feed intake and body weight gain increased momentously by the addition of ginger flowers and leaves; however, the drink intake and hematological analysis remained non-significant by the addition of ginger parts. Originality/value Conclusively, it was revealed that leaves have more hypoglycemic potential as compared to flowers.

Scanty Information

Asparagus africanus Lam. is a plant used traditionally to treat different ailments. Currently, scanty information is available on its safety. The aim of this study is to determine the acute toxicity of the methanolic extract on vital organs and its associated biochemical parameters. Fifteen female Sprague-Dawley rats were divided into five groups. Group I served as normal control, groups II, III, IV, and V were orally administered single dose of crude extract dissolved in distilled water at 5 mg/kg BW, 50 mg/kg BW, 300 mg/kg BW and 2,000 mg/kg BW. Rats were observed for 14 days and body weights were recorded. On day 15, the rats were sacrificed and blood samples were collected for biochemical and haematological analyses, while the liver and kidneys were sampled for histopathological examination. Body weight and haematology parameters results showed significance difference (p < 0.05) among means of HGB, RDW, RBC, and MCHC; likewise, (p < 0.001) for WBC and platelet among treated groups. Histopathology result showed that kidneys appeared normal while livers were congested with mildly swollen hepatocytes and occasional binucleation. Focal lobular hepatitis was observed in all treated animals. However, hepatic enzymes were not significantly affected and no histopathological harmful effects were observed in kidney. In conclusion, methanolic extracts of A. africanus are safe up to 2,000 mg/kg BW. The obtained results could be used as a justification for the traditional application of the plant for treatment of various ailments.

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.

Acalypha Indica

Acalypha indica is one of the medicinal plants that have been used since ages to treat various diseases such as pneumoniae, asthma and skin diseases. This study aimed to explore the subchronic toxicity effect of Acalypha indica on Sprague Dawley rats based on haematological and biochemical parameters. The extract of Acalypha indica was prepared by aqueous extraction technique. 48 Sprague Dawley rats aged 7 weeks, weighing 150-200g were randomly divided into four groups, 6 animals per gender. A control group received water vehicle while three treated groups received the extract at dosage of 100 (low dosage group), 200 (medium dosage group) and 300 (high dosage group) mg/kg body weight. The sample was administered orally by using oral gavage daily for 90 days. No sign of toxicity and mortality was recorded in all groups throughout the study. There were no significant different (p>0.05) in body weight gain, food and water intake between control and treatment group. However, there was significant different in uric acid between control and high dosage group of male and female rats but the mean were in normal range. There were also reduced in mean of urea and creatinine in all dosage group of male and urea for all dosage group of female. Statistically significant reduced in urea was recorded between control and high dosage group of male only. Other parameters showed no significant different between control and treatment groups. Therefore, Acalypha indica is safe for human consumption and might be potential in reducing kidney damage problem.

Patterns of eating behavior, body weight gain, and hormone changes were examined in normal-weight albino Sprague-Dawley rats on macronutrient diets. These diets consisted of either three separate jars with pure macronutrients, fat, carbohydrate and protein, from which to choose, or a single diet with different concentrations of fat and carbohydrate. Similar patterns on the choice-diet and single-diet paradigms were observed. During the first 7–10 days on these diets but not subsequently, the rats consuming a fat-rich diet exhibit significant hyperphagia, an increase in both total and fat intake that produces higher body weight gain. Compared with a 10% fat diet, a 30% fat diet is associated with a decline in insulin and corticosterone (CORT) levels, whereas a 60% fat diet produces an increase in circulating glucose. Levels of glucose are positively correlated with fat intake, and together these measures are consistently related to body fat. These relationships are most strongly expressed in rats that consume a fat-rich diet with >30% fat. Whereas insulin levels are also positively related to body fat, CORT is inversely related in these normal-weight subjects. In animals consuming a high-fat diet, a clear separation can be seen between “obesity-prone” (OP) rats with 100% greater body fat than “obesity-resistant” (OR) rats. The OP rats, which consume 15% more total calories, have significantly higher insulin and glucose levels. In animals that consume a diet with >30% fat, it is the OP but not the OR rats that exhibit a positive relation between fat intake, glucose levels, and body fat and reveal an additional association between carbohydrate intake, insulin, and body fat. Thus these rats on macronutrient diets exhibit distinct traits that relate behavior to hormone disturbances and adiposity and distinguish subjects that are prone vs. resistant to obesity.

l-(+) Ergothioneine is a naturally occurring thiol amino acid with antioxidant properties and potential benefits as a dietary supplement. Despite its century-old identification and wide distribution in human food, little is known of its mechanism of action and safety. The nature-identical biomimetic of l-(+) ergothioneine, produced by Mironova Labs and supplied as Mironova (EGT+), has been investigated in the present studies for its mutagenic and toxicologic potential. In a plate incorporation and preincubation assay with Salmonella typhimurium strains TA98, 100, 1,535, and 1,537 and Escherichia coli WP2uvrA strain, at dose concentrations of 1.58, 5, 15.8, 50, 158, 500, 1,580, and 5,000 μg/plate with and without metabolic activation, no cytotoxicity or mutagenicity was observed. Following a preliminary 28-day study, a repeated dose 90-day gavage study at dose levels of 0, 400, 800, and 1,600 mg/kg body weight (bw)/d in Sprague Dawley rats, in which dose-proportional systemic absorption was confirmed by plasma analysis, no adverse clinical, body weight/gain, food consumption and efficiency, clinical pathology, or histopathological changes associated with the administration of the nature-identical ergothioneine were observed. In conclusion, EGT+ administered over 90 days was well tolerated with a no adverse effect level at 1,600 mg/kg bw/d, the highest dose tested for male and female rats. In addition, the nature-identical test substance, EGT+ was not mutagenic in a bacterial reverse mutation assay at plate concentrations of up to 5,000 μg/mL in the presence or absence of metabolic activation.

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.

Wood Creosote

Seirogan, an herbal medicine containing wood creosote (tablets, 10.0% w/w), has been developed and marketed for almost a century in various countries for the control of acute diarrhea and treatment of associated symptoms, such as abdominal cramping. Wood creosote (CAS no. 8021–39–4) is a mixture of simple phenolic compounds, including guaiacol and creosol and related compounds, and is chemically distinct from, and should not be confused with, coal tar creosote, a known carcinogen. In the current study, the oncogenic potential of wood creosote was assessed in a 96/103-week oral gavage study in Sprague-Dawley rats. Groups of 60 rats/sex received wood creosote at dose levels of 20, 50, or 200 mg/kg body weight [bw]/day. An additional group of rats received the vehicle, 0.5% carboxymethylcellulose in deionized, distilled water, at the same dose volume as the treatment groups (10 ml/kg) and served as the controls. Treatment-related decreases in survival, body weight, and food consumption, as well as increased incidences of clinical signs that included rales, decreased activity, and salivation, were noted at 200 mg/kg bw/day when compared with the control group. There was an increased incidence of reddened and edematous lungs in rats from the 200 mg/kg bw/day group that died during the study. The lung findings were suggestive of test article aspiration during dose administration or agonal aspiration preceding and possibly resulting in death, especially because these observations were not seen in animals that survived to scheduled sacrifice. Additionally, phenols are generally recognized as having corrosive properties. There were no changes in clinical pathology and no increases in neoplastic or non-neoplastic lesions, excluding the lung findings, related to treatment with wood creosote at any dose level. Although the results of this study indicate that the maximum tolerated dose of wood creosote was met or exceeded at 200 mg/kg bw/day, there was no evidence of oncogenicity at any dose level. The lack of any evidence of oncogenicity supports the safety profile of the active ingredient in Seirogan, wood creosote.

This study investigated the antidiabetic activity of Cinnamomum cassia (C. cassia, Cc) silver nanoparticles (CcAgNPS) and effects of C. cassia on the kidneys of rats with induced type 2 diabetes. Twenty-four Sprague-Dawley rats weighing 250 ± 20 g were induced with diabetes by intraperitoneal injection of streptozotocin (STZ, 60 mg/kg). Animals were randomly assigned to one of four groups (n = 6) and treated for eight weeks with normal saline (control, group A), 5 mg/kg of CcAgNPs (group B), 10 mg/kg of CcAgNPs (group C), or 200 mg/kg of Cc (group D). Body weight and fasting blood glucose (FBG) was measured weekly and fortnightly, respectively. At the end of experiments, animals were euthanized, blood and kidney tissue samples were collected for biochemistry (oxidative stress markers and renal function parameters) and kidneys were harvested for histology (PAS and HE staining). Body weight was significantly higher in group B and C vs. control (p < 0.05), while no significant differences were observed in the kidney-to-body weight ratio between groups. FBG, glutathione, malondialdehyde, alanine aminotransferase, aspartate aminotransferase, serum urea and creatinine were significantly lower in group B, C and/or D vs. control (all p < 0.05). In group A, severe distortion of the glomerular network was observed, marked by the loss of capsular integrity, thickened basement membrane, tubular cells with pyknotic nuclei, vacuolization, and interstitial space with infiltrations. These adverse effects were mitigated by 5 mg/kg and 10 mg/kg of CcAgNPs. Our study confirms structural and functional damage to kidneys caused by diabetes. CcAgNPs have a regenerative potential in diabetes-induced kidney damage and may be used as an antidiabetic agent.
