Picria fel-terrae extract has been investigated for its hepatoprotective activity. This current study was conducted to evaluate the subchronic toxic effect of Picria fel-terrae Lour. leaf extract. The subchronic toxicity of ethanol extract of P. fel-terrae leaf was evaluated by OECD (Organization for Economic Cooperation and Development) guidelines. The extract at doses of 125, 250, 500, 1000 mg/kg body weight (BW) were orally administered to the test animals for 90 days. Signs of toxicity and mortality were observed for 90 days and 118 days. The biochemistry, hematology, macropathology, relative organ weight and histopathology examination was also performed. The macroscopic and microscopic examinations of liver, lung, kidney, spleen and heart displayed normal color and texture after treatment, with ethanol extract P. fel-terrae leaf at doses of 125 and 250 mg/kg BW. The signs of toxicity, mortality, macroscopic and microscopic changes, as well as increasing biochemistry parameters were observed after treatment, with extract at the dose of 500 and 1000 mg/kg BW. However, the abnormal value of biochemistry parameters was returned to normal when the treatment was stopped. There was no effect on hematological parameters at all doses of extract. The ethanol extract P. fel-terrae leaf is untoxic for long-term use at dose 125 and 250 mg/kg BW. The toxic effect of P. fel-terrae at 500 and 1000 mg/kg BW was reversible.

This study was designed to investigate the effects of the different extracts of Chromolaena odorata leave on the hematopoietic system of Wistar rats. Solvent extraction was used for the ethanol and aqueous extractions while decoction method was used for the crude extraction. Fifty Wistar rats of both sexes weighing 140-180 g were used for this study. They were divided into ten groups each containing five rats. The animals were fed the extracts by oral gavage once daily for 21 days. Blood sample was collected via cardiac artery. Hematological parameters were analyzed using automation method. The ethanol extract gave the highest extract yield. The aqueous, ethanol and crude extraction had median lethal toxicity (LD50) of 2738.6 mg/kg, 1581.1 mg/kg and 224.7 mg/kg, respectively. Significant difference (P<0.05) in the total white blood cell count was observed in the 75 mg/kg ethanol and 300 mg/kg crude extracts when compared with control group. Significant difference (P<0.05) in the hemoglobin concentration was observed in the 150 mg/kg ethanol extracts when compared with the control group. Significant difference (P<0.05) in the packed cell volume was seen in the 75 mg/kg aqueous, 150 mg/kg aqueous and 75 mg/kg ethanol extracts in respect to the control group. The mean cell volume, the mean platelet volume and platelet large cell ratio of the 75 mg/kg aqueous extract were significantly different (P<0.05) when compared with the control group. The present study showed possible treatment-induced hematopoietic function of C. odorata leave extracts.

Background: Ayurvedic literature indicated use of Bryonia laciniosa (BL) for metabolic abnormalities. However only one study evaluated Bryonia laciniosa seed ethanolic extract in streptozotocin-induced diabetes in rats and was found to have anti-hyperglycemic and anti-hyperlipidemic effects. The authors looked at the renal function test in addition and found that it prevents deterioration of renal function in rats. Hence it was interesting to find if Bryonia laciniosa had any protective action in streptozotocin induced diabetic nephropathy in rats.Methods: Streptozotocin induced diabetic nephropathy model in wistar rats was standardised in phase 1. In phase 2 animals were divided into 4 groups and diabetic nephropathy was induce with STZ. Vehicle Control group animals received CMC 0.5%, Positive control group received enalapril 5 mg/kg, Test group 1 received ethanolic extract of Bryonia laciniosa (EEBL) 250 mg/kg and Test group 2 received (EEBL) 500 mg/kg from 3rd day onwards till 6 weeks. Renal function, morphology and histopthological changes were evaluated.Results: There was a significant reduction (p <0.001) in the serum creatinine and BUN in both low and high dose EEBL groups. High dose of EEBL lowered raised MDA values significantly (p<0.001) and raised the GSH values (p<0.001). On histopathology, the high dose EEBL reversed nephropathic changes which were equivalent to enalapril.Conclusions: Bryonia lacinosa in high doses 500 mg/kg has potential to reverse diabetic nephropathic changes induced in wistar rats.

Today the questions about possibility of development disturbances in the immune system of the fetus and the newborn in chronic toxoplasmosis are poorly understood. Aim of research: to detect immunological disturbances in the offspring of rats which have been administered antigens T. gondii.Two series of experiments was performed. In these experiments white female Wistar rats in the III trimester of pregnancy have been administered corpuscular antigen T. gondii. The 60 days-old offspring of these rats have been included in study group of 137 animals. CD3+ cells count was performed in peripherical blood and standard suspension of splenocytesrats offspring. Peripherical blood cells count was performed in the blood of the rats offspring. In the second experiment rats offspring have been administered sheep erythrocytes in 5 days, before euthanasia. In spleen of this rats antigen-produced cells was counted.In control group was included 118 animals, which was born from white female Wistar rats have been administered 0,9% NaCl solution. CD3+ cells was detected in Cytomics FC500 flow cytometry analyzer (Beckman Coulter,USA) by use rats origne-specifed monoclonal antibodies Anti-Rat CD3-FITC (Beckman Coulter,USA). Hematological parameters was assessed by use hematological analyzer Excell-22 (USA).We observed, that CD3+ lymphocytes and antigen-produced cells was decreased in test group (degress of decrease CD3+ cells was 17,2%; р = 0,003 in spleen vs. control group, degress of decrease antigen-produced cells was 27,3%; р = 0,03 vs. control group). Number of leukocytes was increased in in test group (34,5%; р = 0,009 vs. control group). Power and strength correlation pleiades between studied blood and spenal markers were higher in in test group vs. control group (∑Gi = 16; ∑Di = 4,38 vs. ∑Gi = 13; ∑Di = 2,28). This phenomenon is probably due to the development adaptive reactions disruption in the immune system and development secondary immunodeficiency states in the offspring of rats.Violations of immunoreactivity, as well as disruption the possibility of operational restructuring of the immune system and choosing the best immune response in the offspring of rats whose perinatal development take place under the effect of antigens T. gondii, persists for a long time – within 60 days of postnatal life.
