Objective: This research was conducted to determine the acute toxicity of ethanol extract of velvet beans (Mucuna pruriens) from Indonesia. Extract of Indonesian Mucuna pruriens seeds showed antiparkinson activity due to the presence of L-DOPA inadequate levels. However, research on the toxicity level of Mucuna pruriens seeds from Indonesia is still limited. Acute toxicity data are needed to make Mucuna pruriens as standardized herbal medicine for Parkinson disease.Methods: The dried seed of Mucuna pruriens was extracted by ethanol and suspended with tragacanth to make several dosas of ethanol extract of Mucuna pruriens seeds. Determination of acute toxicity was performed on six groups, each consisting of five Wistar rats. One group was used as a control group; other groups were given ethanol extract of Mucuna pruriens seeds orally at a dose of 5 mg/kg, 50 mg/kg, 300 mg/kg, 2000 mg/kg, and 5000 mg/kg body weight. Symptoms of toxicity, including death, were observed daily for 14 d. At the end of the observation, the surviving Wistar rats were autopsied and the brain, heart, liver, lungs, stomach, spleen, kidneys, and ovaries were weighed to give relative organ weight.Results: There was no mortality observed in all groups. The Wistar rats gained weight within the normal range. The relative organ weights in all groups generally did not show a significant difference. However, the significant differences (P<0.05) were seen in the liver for all treatment groups compared to the control group.Conclusion: The ethanol extract of Mucuna pruriens seeds from Indonesia administered orally has LD50>5000 mg/kg, thus it could be regarded as safe or non-toxic. However, this extract may be potentially toxic to the liver

Background and Objective: Rheumatoid arthritis (RA) is an autoimmune disease characterized by failure of spontaneous resolution of inflammation with lifetime perseverance, becoming principal cause of inactivity. Many conventional therapies are in use but the side effects associated with them are equally problematic. Therefore an urge to explore advanced therapeutic approaches with least adverse events has seeded the idea of discovering newer herbal drugs and their respective constituents in management of RA. The current research explores anti-arthritic activity of Terminalia catappa fruits hydroalcoholic extract in CFA induced Wistar rats. Methods: The fruits were obtained, washed, dried and processed to obtain hydroalcoholic powdered extract which was dissolved in water and given orally to the rats. Wistar rats of either sex were used in the study. The animals were injected with 0.1 ml of complete freund’s adjuvant (CFA) in footpad of left hind paw. The treatment was initiated from day 0 by oral dosing of Terminalia catappa fruit extract in doses of 40 mg/kg and 80 mg/kg followed by CFA administration to day 21 and behavioral, hematological parameters besides histopathological screening were assessed simultaneously. Results: The arthritic symptoms were observed to gradually decrease in treatment groups when compared against disease control groups. The parameters like body weight and pain latency were increased whereas paw volume and arthritic score were found to significantly decrease in treatment groups as compared to disease control group. The hematological parameters were also modified and were studied in treatment groups. The histopathological estimation depicted extent of damage in joint tissue of diseased rat comparable to normal, standard and combination therapy group. Conclusion: The fruits possess anti-arthritic properties and significantly reduced paw volume, arthritic score and increased pain threshold and body weight gain besides theory hematological effects like increase in Hb and RBC and decrease in WBC, platelets and ESR levels simultaneously. The histopathological estimation confirmed decreased deterioration of joint tissue in treatment groups as compared to disease control group hence proving to be an emerging therapeutic option in management of RA.

Dacryodes edulis (African pear) seed has a long history of use in ethnomedicine. However, there is a paucity of information on its ameliorative potential on hepatic damage. In the present study, the potentials of D. edulis ethanolic seed extract (DET) in attenuating carbon tetrachloride (CCl4)-induced hepatotoxicity in male Wistar rats was assessed. Ninety male Wistar rats were divided into 3 groups (n = 10) designated: control, CCl4, and DET, respectively. Animals in the control group were administered 2 mL/kg body weight corn oil, while those assigned to CCl4 and DET groups were administered i.p. 30% CCl4 in corn oil (1:1 v/v) at 2 mL/kg. Treatment was administered once every 24 h consecutively for 72 h. Thereafter, control and CCl4 groups were treated once daily with 1 mL distilled water by gavage, while DET rats were treated once daily with 1500 mg/kg DET by gavage. At every 7 days interval and for 28 consecutive days, animals were starved overnight, weighed, and six rats from each group were sacrificed under anesthesia to collect blood and liver samples. After 28 days, remarkable improvements in feed intake, body weight, serum levels of hepatic function indicators, and hepatic histology were observed in DET rats compared to CCl4 rats. These results suggest a possible ameliorative potential of D. edulis ethanolic seed extract against CCl4-induced hepatic injury.

<p>Green Algae, an organism with active substance such as phytomelatonin, has potential to be developed as Indonesian traditional medicine. As the long term addition of Green Algae ethanol extract (<em>Ekstrak etanol ganggang hijau</em>, EEGH) influences the hematology system, in this paper, the safety test was done to ensure the safety of its use through subchronic toxicity test of EEGH on the hematology parameters of Wistar rats. The test group consisted of three groups treated with EEGH 100 mg/kg, 200 mg/kg, and 400 mg/kg, while the control group was given by 0.5% CMC-Na, with 8 rats each respectively. By using blood samples taken from orbital sinus on the 29<sup>th</sup> day, common hematologic parameters (erythrocytes, leukocytes, and hemoglobin level), the parameters of hemostasis (platelets, pT, aPTT, BT) and immune parameters (Differential Leukocytes Counts include neutrophils segment, lymphocytes, monocytes, and eosinophils) were finally observed and showed that the 28 days-addition of EEGH increase the hematological parameters of Wistar rats.</p>

Abstract Introduction: Calabash chalk is a naturally occurring mineral, chiefly composed of fossilized sea shells. It is prepared from clay and mud mixed with other ingredients, including lead, arsenic, sand and wood ash. Clay consumption is correlated with pregnancy, and also to eliminate morning sickness in women. The aim of this study is to evaluate the effects of calabash chalk on the ovarian function in adult female Wistar rats. Methods: Eighteen (18) adult female Wistar rats. Group A served as the control group, group B received 40 mg/kg body weight of Non-salted calabash chalk while group C received 40 mg/kg body weight of Salted calabash chalk for 14 days. On day 15, the animals were sacrificed for histological and biochemical examination. Results: Results showed a significant (P< 0.05) reduction in follicle stimulating hormone (FSH) levels of the treatment groups when compared with the control group and an increase in luteinizing hormone (LH) levels of the treatment groups when compared with the control group. Histological examination of the ovaries showed severe deterioration of the ovarian follicles, necrosis and follicular atresia. Conclusion: Calabash chalk is toxic to ovarian function. These alterations have been shown to be the leading cause ofinfertility in female rats. Hence, proper monitoring, education, and regulation of the product is needed.
