Anthelminthic effects of artemisinin and its derivatives
(2013) Tawewan Tansatit; Mahidol University. Faculty of Veterinary Science. Department of Pre-clinic and Applied Animal Science
Qinghao (Artemisia annua, L.), a famous herb from China, has been used in traditional Chinese medicine. Artemisinin, an active substance is extracted from the leaves and flowers of Qinghao, with a unique sesquiterpene lactone endoperoxide structure showing an antimalarial activity. Derivatives of artemisinin, artesunate and artemether, are the most widely used as antimalarial drugs. Since artemisinin not only possess antimalarial properties, but also active against various parasitic infection. Ongoing research on these compounds has been emphasized on the potential impact for anthelmintic treatment. Artemisinin derivatives exhibited a broad spectrum property against various trematodes, nematode, and cestode both in vitro and in vivo studies. These helminthocidal properties of artemisinin derivatives presented here provide further data for clinical investigations in the field trial study. However, a better understanding of action of artemisinin derivatives and their biomolecule target may contribute a promising possibility for clinical utility in anthelmintic application. Toxicity of artemisinin derivatives was less and was demonstrated in experimental animals with neurotoxicity and anemia.

This study aimed to compare academic achievement (GPAX) of the students in Faculty of Veterinary Science, Mahidol University between the students who admitted by quota system and Central University Admissions System (CUAS) in academic year 2010. The 254 students of the 1st-6th year were evaluated. The data were analyzed by percentage, mean and standard deviation. The results were presented as: 1) The academic achievement of the CUAS admitted students was higher than the quota system admitted students in the 1st, 2nd, 4th and 6th year students. 2) The academic achievement of the CUAS admitted students was higher than the quota system admitted students in the veterinary preparation level whereas the academic achievement in pre-clinical and clinical levels of the quota system admitted students was higher than the CUAS admitted students.

The aim of this study was to investigate the effect of supplementation of L-Cysteine in Modified Kenny's extender on chilled stallion semen quality at 5oC. Semen samples were collected from 3 stallions by artificial vagina and centrifugation to remove seminal plasma and diluted with Modified Kenny's extender to 50 x 106 sperm/ml. Semen samples (n=10 ejaculates) were divided into 3 portions, the first portion as the control (KE), the second portion was added with L-Cysteine 200 μmol/l (KEC200) and added L-Cysteine 400 μmol/l in the last portion (KEC400). In all samples, the percentage of progressive motility, viability and acrosome integrity were evaluated at 0, 24, 48 and 72 h after storage at 5oC. There were a significant (P < 0.05) lower percentage of dead spermatozoa in group KE200 than other groups at 24 h. There was a significantly lower percentage of progressive motility in KEC 400 compared toother groups at 48 h (P < 0.05). In addition, there was a tendency (P = 0.1) of lower percentage of dead spermatozoa in group KE200 than other groups at 48 h. At 72 h, comparing all groups, a higher percentage of viability in groups KEC200 and KEC400 was found, but not statistically significant. In conclusion, Addition of L-cysteine at a concentration of 200 μmol/l to the Modified Kenney's extender tend to improve the stallion chilled semen progressive motility, dead/alive, viability and acrosome integrity during chilled storage at 5oC for 48 h.
