Diabetes mellitus is metabolic syndrome that causes disability, early death, and many other complications. Currently insulin and many synthetic drugs are used in diabetes treatment. However, these pharmaceutical drugs are too expensive particularly for sub-Saharan population in addition to their undesirable side effects. The present study was aimed to evaluate antidiabetic effect and toxicity level ofArtemisia afrawhich was collected from its natural habitat in Bale Zone, around Goba town, 455 km southeast of Addis Ababa. Air dried aerial parts ofArtemisia afrawere separately extracted with both distilled water and 95% methanol. Oral acute toxicity test was conducted on healthy Swiss albino mice. Antidiabetic effect of the aqueous and methanolic extracts ofArtemisia afrawas separately evaluated on alloxan induced diabetic mice at doses of 500, 750, and 1000 mg/Kg body weight orally. The results indicate that mean lethal dose (LD50) for aqueous extract ofArtemisia afrawas 9833.4 mg/Kg. Blood glucose level was significantly decreased by 24% (p<0.005) and 56.9% (p<0.0004) in groups that received aqueous extract ofArtemisia afraat dose of 500 mg/Kg and 750 mg/Kg, respectively. The methanolic extract ofArtemisia afraalso significantly lowered blood glucose by 49.8% (p<0.0001) at doses of 1000 mg/kg on the 5th hr. Aqueous extract ofArtemisia afrawas regarded as nontoxic and safe since its LD50was found above 5000 mg/Kg. Aqueous extract showed higher effect at relatively lower dose as compared to methanolic extract. The aqueous extract was screened positive for phytochemicals like flavonoids, polyphenols, and tannins that were reported to have antioxidant activity.

To evaluate the effect of Aqueous extract of Terminalia belliricafruit pulp (AETB) on learning by Hebb William maze model in mice with acute alcohol consumption.Swiss albino mice (n=48) of either sex weighing 20-30g will be divided into eight groups of six mice each. Drugs were given orally after 12 hours of fasting. Group I mice received 10ml/kg of Normal Saline, Group II mice received Piracetam 200mg/kg, Group III received AETB 36mg/kg, Group IV received ethanol 1.5g/kg orally, Group V received ethanol(1.5g/kg )+ piracetam (200mg/kg), Group VI mice received ethanol(1.5g/kg) +AETB(9mg/kg), Group VII mice received ethanol(1.5g/kg) +AETB (18mg/kg), Group VIII mice received ethanol(1.5g/kg) +AETB(36mg/kg). Time taken by the animal to reach the reward chamber from the start chamber (TRC) in Hebb-William maze was used as a parameterto evaluate the learning.Acute alcohol administration showed increase in TRC. Whereas, acute administration of Aqueous extracts of Terminalia belliricafruit pulp showed a decrease in TRC when compared to the control group. The TRC values for the groups that were administered AETB along with acute alcohol administration showed decrease in TRC values compared to the negative control.Current study showed acute alcohol administration caused impairment of thelearning ability in mice. Whereas, acute administration of Aqueous extracts of Terminalia belliricafruit pulp (AETB)caused enhancement of learning. Pre-treatment with AETB before acute alcohol administration indicated protective action of AETB on alcohol affected learning in mice.

Protection Index

The study reports antidotal efficacy of three HNK [ bis quaternary 2-(hydroxyimino)-N-(pyridin-3yl) acetamide derivatives] and pralidoxime (2-PAM), against soman and tabun poisoning in Swiss albino mice. Protection index (PI) was determined (treatment doses: HNK oximes, ×0.20 of their median lethal dose (LD50) and 2-PAM, 30 mg/kg, intramuscularly (im)) together with atropine (10 mg/kg, intraperitoneally). Probit log doses with difference of 0.301 log of LD50 of the nerve agents administered and inhibition of acetylcholinesterase (AChE) activity by 50% (IC50) was calculated at optimized time in brain and serum. Using various doses of tabun and soman (subcutaneously (sc)), in multiples of their IC50, AChE reactivation ability of the oximes was studied. Besides, acute toxicity (0.8× LD50, im, 24 h postexposure) of HNK-102 and 2-PAM was also compared by determining biochemical, hematological variables and making histopathological observations. Protection offered by HNK-102 against tabun poisoning was found to be four times higher compared to 2-PAM. However, nearly equal protection was noted with all the four oximes against soman poisoning. HNK-102 reactivated brain AChE activity by 1.5 times more than 2-PAM at IC50 dose of soman and tabun. Acute toxicity studies of HNK-102 and 2-PAM showed sporadic changes in urea, uric acid, aspartate aminotransferase, and so on compared to control group, however, not supported by histopathological investigations. The present investigation showed superiority of newly synthesized HNK-102 oxime over standard 2-PAM, as a better antidote, against acute poisoning of tabun (4.00 times) and soman (1.04 times), in Swiss albino mice.

The Molybdenum disulfide nanosheets (MoS2-NSs) thin films has received increasing attention recently due to their versatile multi functionality including catalytic properties, photoluminescence and flexibility, which suggests their future, uses for biomedical applications. However, there are no studies in detail related with biocompatibility of MoS2 thin sheets. Here, weevaluated the dose-dependent effects of MoS2-NSs on cell viability (MTT assay) and release of lactate dehydrogenase (LDH) into culture media using MG-63 cells, as well as haemolysis, hematological, serum biochemical, antioxidants and histopathological parameters in Swiss albino mice. The MoS2-NSs was synthesized via facile hydrothermal method and characterized using XRD, Raman, SEM, TEM and HRTEM. The in vitro study results suggest that at lower concentration MoS2-NSs does not causes any toxicity. The lethal dose (LD50) was evaluated by intraperitoneal administration with different concentrations and estimated as ~1.0 mg kg-1. The higher dose (1.5 mg kg-1) of MoS2-NSs showed significant alteration in hematological markers and serum biochemical enzymes, as compared to control. Lipid peroxidation also shows significant alteration with respect to the control. Histopathological, hematological and biochemical examination, revealed no remarkable changes at lower concentration (less than 1.0 mg kg-1), however, higher concentration (1.5 mg kg-1) causes significant histopathological, antioxidants and biochemical alterations in tissues and serum, respectively. The results suggest that the lower concentration of MoS2-NSs can be used in future biomedical applications.
