Aims: Distemonanthus benthamianus is a widespread plant in West Africa. The bark of its stem is used popularly to treat a variety of illnesses, including fever, bronchitis, rheumatism and malaria. The objective of this work is to evaluate the antipyretic activity of the aqueous extract of the bark of Distemonanthus benthamianus. Materials and Methods: The aqueous extract of the bark of D. benthamianus was tested for their acute oral toxicity in rats. Antipyretic activity was studied in rats of the Wistar strain made feverish after subcutaneous injection of an aqueous suspension of brewer's yeast (Saccharomycete cerevisiae) 20% compared to aspirin. Results: This study showed that administration of the extract at doses of 300, 2000 and 5000 mg / kg / kg dry extract in rats showed no acute toxicity or adverse effects. The results showed that the best antipyretic activity of the extract was recorded at a dose of 800 mg / kg, at the third hour, with a decrease in fever from 39.29 ± 0.14°C to 37.75 ± 0.25°C, i.e. a percentage inhibition of 57% against 62% for the standard molecule (p> 0.05). At this dose, CRP was 3.85 ± 0.1 mg / L compared to that of the healthy control which was 2.78 ± 0.35 mg / L. The results of the albumin assay did not show a significant difference between the treated and untreated fever groups and the healthy control group. In addition, the results showed that the leukocyte level in the feverish control rats is very high (18.84 103 / mm3 of leukocytes) compared to the healthy and treated control rats. Conclusion: The aqueous extract of the bark of Distemonanthus benthamianus is not oral toxic and has interesting antipyretic activities similar to aspirin. The results obtained confirm the validity of the traditional indication of this plant in the management of fever by African populations.

Ammi visnaga L (A.V.) is used in the traditional medicine for the treatment of kidney stones, diabetes and vitiligo. An in vivo anti-psoriasis, anti-inflammatory activities and oral toxicity studies of aqueous extract from seeds of Ammi visnaga L. was investigated. In the acute toxicity, the extract was administered orally in a single dose to rats (0- 2000-5000 mg/kg) and in the sub-acute toxicity daily for 28 days (0-300-600-1000 mg/kg/day). The symptoms of toxicity and mortality have been recorded daily and during 14 days of recovery with an examination of liver, kidney, hematologic, biochemical and histological analysis at the end of treatment. The anti-inflammatory activity was evaluated by induction of oedema and the anti-psoriasis by induction of a psoriasiform-like skin phenotype by UV-B radiations. No mortality was observed after single gavages by a dose up to 5000 mg/kg and no signs of toxicity noted. Clinical and biochemical examination during 28 days of gavages at all doses showed no significant difference compared to control group, while a significant reduction in MCV (mean corpuscular volume) and P-LCR (platelet large cell ratio) (p <0.05), PDW (platelet distribution width) and MPV (multi-purpose vehicle) (p <0.01) was observed and histopathological examinations showed slight inflammation in the liver and kidneys for the higher dose. Percentage of inhibition of the oedema was near the positive control 50% for all doses tested. Treatment with A.V. extract had decreased the thickness of the skin induced by UV-B irradiation.  In conclusion, the LD50 was estimated greater than 5000 mg/kg; therefore A.V. can be classified as non-toxic but if used in the long term can induce a slight toxicity dose dependant with high anti-psoriasis and anti-inflammatory activities.

Aristolochia longa L. (Aristolochiaceae) is widely used to treat breast cancer in Algerian traditional medicine. The present study was conducted to investigate the effects of ingestion of aqueous extracts of different parts of the plant on liver and kidney functions in wistar albinos mice. Acute oral toxicity was performed to determine DL50, this toxicity was carried out by the oral administration in single doses of 0–12 g/kg for tubers aqueous extracts and 2 g/kg and 5 g/kg for aerial and fruit aqueous extract respectively.  General behavior, adverse effects and mortality were determined for up to 14 days. The animals were sacrificed and biochemical study was done. The acute oral toxicity result revealed that LD50 of the tubers and fruit aqueous extracts was respectively more than 12 g/kg and 5 g/kg, but DL50 of the aerial aqueous extract was at 5 g/kg. The result revealed also that liver and kidney function of different groups receiving high doses was affected as ASAT, ALAT, Urea, creatinine was significantly increased as compared to control group. Histological examination showed alterations of the renal parenchyma and the liver which is greater in animals treated with high dose. Thus, caution should be exercised with its usage.

Purpose: This study aimed to compare the neutrophil-to-lymphocyte (NLR) and plateletto- lymphocyte (PLR) ratios in patients with retinal artery occlusion (RAO) with those from a healthy control population and to identify the relationship between them. Methods: Forty-six patients with RAO and fifty-one healthy control subjects were included in this retrospective case-control study. RAO was diagnosed following an ophthalmic examination and fluorescein angiography (FA). Blood neutrophil, lymphocyte, and platelet counts were recorded for each of the 97 subjects, from which NLR and PLR values were calculated. Results: There were 46 patients (28 male [M], 18 female [F]) in the RAO group and 51 patients (27 M, 24 F) in the control group. No significant differences were found between patients with RAO and the control subjects in terms of gender and age (P > 0.05). Patients with RAO had significantly increased NLR values (2.85 ± 1.70) than the control subjects (1.63 ± 0.59, P < 0.001). The mean PLR in patients with RAO was 123.69 ± 64.98, while that in control subjects was 103.08 ± 36.95; there was no significant difference between the two groups (P = 0.055). A logistic regression analysis revealed that NLRs were 3.8 times higher in patients with RAO than in control subjects (odds ratio = 3.880; 95% confidence interval = 1.94 to 7.74; P < 0.001). Conclusion: NLRs were significantly increased in patients with RAO compared to the control subjects.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

OBJECTIVES: To evaluate the Immunomodulatory, apoptosis induction and antitumor effects of aqueous and methanolic extracts of Calvatia craniiformis regarding the size of tumour mass, caspase-8 expression and apoptotic index (AI%) in mice transfected with murine hepatocellular carcinoma cell line (H22) as an experimental therapeutic system for human hepatocellular carcinoma.MATERIAL AND METHODS: Forty-eight Balb/C albino mice were transfected in legs with H22 cells. Tumour size was measured twice a week. Caspase-8 protein expression and apoptotic index determination evaluated by Immunohistochemistry.RESULTS: Tumor size significantly differed between the two groups of mice transfected with H22 cells; the first was treated with C. craniiformis aqueous extract (0.3, 0.6, 1.2) mg/kg and the second group was treated with C. craniiformis methanolic extract (0.25, 0.5, 1.0) mg/kg compared with control group. The inhibitory activity of aqueous and methanolic extracts was dose and duration dependent. The size of the tumour mass was reduced up to 87.9% when treated with 1.2 mg/kg aqueous extract and 1 mg/kg for methanolic extract. Caspase-8 expression was increased in a dose-dependent manner among H22 bearing mice treated with C. craniiformis aqueous extract (0.3, 0.6, 1.2) mg/kg. At 0.3 mg/kg, the intensity of expression was strong in (33.33%) and very strong in (66.67%). While at 0.6 mg/kg and 1.2 mg/kg the intensity of expression was strong in (33.33%) and very strong in (100%) with a significant difference (P ≤ 0.001). H22 bearing mice treated with (0.25, 0.5, 1.0) mg/kg C. craniiformis methanolic extract shows increased caspase-8 expression in a dose-dependent manner. At 0.25 mg/kg, the intensity of expression was strong in (33.33%) and very strong in (66.67%). While at 0.5 mg/kg, the intensity of expression was strong in (33.33%) and very strong in (100%). At 1.0 mg/kg, the intensity of expression was strong in (16.67%) and very strong in (83.33%) with significant difference (P ≤ 0.001). AI% of H22 bearing mice treated with C. craniiformis aqueous and methanolic extracts were significantly increased (P ≤ 0.05) compared with the untreated control group. No significant difference was reported in AI% between aqueous and methanolic extracts treated groups.CONCLUSIONS: Extracts of C. craniiformis were highly efficient in tumour growth inhibition, causing a reduction in the tumour size clinically and increase the expression of caspase-8 gene product in tumour tissue, causing increase apoptotic index of H22 cells taken from the legs of inoculated mice leading to loss of legs due to bone necrosis. Antitumor activity of C. craniiformis aqueous, and the methanolic extract was dose and duration dependent.

Background Familial Mediterranean Fever and celiac disease are both related to auto-inflammation and/or auto-immunity and they share some common clinical features such as abdominal pain, diarrhea, bloating and flatulence. Objectives We aimed to determine the association of these two diseases, if present. Methods Totally 112 patients diagnosed with Familial Mediterranean Fever and 32 cases as healthy control were included in the study. All participants were examined for the evidence of celiac disease, with serum tissue transglutaminase IgA levels (tTG IgA). Results Totally 144 cases, 112 with Familial Mediterranean Fever and 32 healthy control cases were included in the study. tTG IgA positivity was determined in three cases with Familial Mediterranean Fever and in one case in control group. In that aspect there was no significant difference regarding the tTG IgA positivity between groups (P=0.81). Duodenum biopsy was performed to the tTG IgA positive cases and revealed Marsh Type 3b in two Familial Mediterranean Fever cases and Marsh Type 3c in the other one while the biopsy results were of the only tTG IgA positive case in control group was Marsh Type 3b. In HLA evaluation of the celiac cases; HLA DQ2 was present in two celiac cases of the Familial Mediterranean Fever group and in the only celiac case of the control group while HLA DQ8 was present in one celiac case of the Familial Mediterranean Fever group. Conclusions We did not determine an association of Familial Mediterranean Fever with celiac disease. Larger studies with subgroup analysis are warranted to determine the relationship of these two diseases.

Withania frutescens (W. frutescens) is a medicinal plant widely used to treat several diseases. This work aims to study phytochemical composition as well as acute and subacute toxicity of W. frutescens hydroethanolic extract in mice. The phytochemical composition of W. frutescens extract was performed using gas chromatographic analysis. Acute toxicity was studied in vivo with oral administration of single doses 400 mg/kg, 1000 mg/kg, and 2000 mg/kg for 14 days. Subacute toxicity was studied with the administration of repeated doses of 400 mg/kg/day and 2000 mg/kg/day for 28 days. Phytochemical analysis of W. frutescens hydro-ethanolic extract confirmed the presence of interesting chemical compounds. Acute toxicity results showed no toxic symptoms in mice treated with an increasing dose up to a maximum of 2000 mg/kg. Alongside acute toxicity, subacute data showed no clinical symptoms nor biochemical or histological alteration in mice treated with an increasing dose up to a maximum of 2000 mg/kg compared to the control group (p < 0.05). This study shows no toxic effects in animals treated with W. frutescens extract, and, therefore, this plant can be considered safe in animals up to 2000 mg/kg under both acute and subacute toxicity conditions.

Abstract Objectives Vitamin K is generally regarded as a procoagulant drug with physicians, concerns have been raised about its effects on hemostasis in the healthy population. We aimed to investigate whether vitamin K2 affects activities of individual vitamin K dependent coagulation factors in healthy individuals without anticoagulation treatment. Methods Forty healthy volunteers between 25 and 40 years old were recruited. They received 90 μg of vitamin K2 every day for 30 days. Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), international normalized ratio (INR), fibrinogen (FIB) levels and blood coagulation factors II, VII, IX, and X activity levels (F II : C, FⅦ : C, FⅨ : C,FⅩ : C), protein induced by vitamin K absence or antagonist-II (PIVKA-II), which is uncarboxylated prothrombin were measured at day 0, and day 30 after vitamin K2 administration. Plasma diluted 1:10 from vitamin K2 group and healthy control group were assayed for the activity of factors II, VII, IX, and X. Results PT, APTT, TT, and FIB did not show significant difference at day 30 when compared with baseline. The activities of coagulation factors II, VII, IX, and X was not significantly different with baseline (97.28 ± 12.42% vs. 99.96 ± 10.24%, P = 0.24 for F II: C; 76.12 ± 15.82% vs. 76.40 ± 12.33%, P = 0.92 for FⅦ: C; 97.65 ± 13.98% vs. 99.65 ± 13.30%, P = 0.47 for FⅨ: C; 89.18 ± 10.76% vs. 92.01 ± 10.46%, P = 0.1 for FⅩ: C) . PIVKA-II levels were not changed with 30 days vitamin K2 supplementation (21.62 ± 3.21 vs. 23.87 ± 2.65 mAU/ml, P = 0.16). After 30 days vitamin K2 administration, factor II, Ⅶ, Ⅸ, and Ⅹ activity of plasma diluted up to 10 times were proportionally decreased, and did not show significant difference with the healthy control without vitamin K2 exposure (10.32 ± 1.24% vs. 10.97 ± 1.55%, P = 0.38 for F II: C; 9.52 ± 2.94% vs. 9.14 ± 1.79%, P = 0.68 for FⅦ: C; 11.78 ± 2.12% vs.11.65 ± 1.54%, P = 0.87 for FⅨ: C; 8.22 ± 1.28% vs. 8.92 ± 1.13%, P = 0.21 for FⅩ: C). Conclusions Vitamin K2 supplementation at recommended dosage does not affect vitamin K-dependent coagulation factors activity in healthy subjects. Uncarboxylated prothrombin (PIVKA-II) in healthy individuals is not decreased with vitamin K supplementation. Funding Sources None.
