JOURNAL OF EDUCATION AND SCIENCE, Volume 17, Issue 1, Pages 48-58

In this study two major groups of albino adult male rats (3-4 months old and 155-262g weight) were used as experimental model for this study. First group contains five healthy rats used as healthy control group. Second group consisted of twenty rats with atherosclerosis induced by hydrogen peroxide and cholesterol, which was further subdivided into four subgroups with five rats in each. First subgroup was orally treated with sunflower oil alone and considered atherosclerosis control group, the second subgroup was treated with 300mg clofibrate drug/kg rat body weight and considered hypolipidemic standard reference group, third and fourth subgroups were orally treated with 5.23 and 10.45mg acetic acid/kg body weight, respectively. Blood samples were collected from retro-ocular eye vein by using heparinized capillary tubes. Plasma total lipid (TL), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-c) and liver total cholesterol (TC) were determined. Nutritional status of the rats was estimated throughout body weight gain and apparent digestibility. Analysis of variance and Duncan test showed that, the acetic acid caused an increase in plasma TL, TC, very low density lipoprotein-cholesterol and low density lipoprotein-cholesterol (VLDL-c+LDL-c), atherogenic indices, and liver TC values and a decrease in plasma HDL-c. Furthermore, body weight losses and bad nutritional status were recorded. Therefore, acetic acid was regarded as a hyperlipidemic material.

Sexual cycle and histomorphological changes in the testes and epididymis of bat male Pipistrellus kuhlii in the Nineveh region - Iraq

Esmail Hassan; Rabee Mohammed

JOURNAL OF EDUCATION AND SCIENCE, Volume 17, Issue 1, Pages 130-148

The present study has shown thai the male bat Pipistrellits kiihli has a reproduction habit that attracts some attention because of the small size of this species , and the fact thai the male bat is effected by environmental conditions ; represented by temperature degree and the length of the photoperiod .In addition to the obligatory coincidence between his sexual cycle and the estrous cycle of the female. Therefore the sexual cycle of male bat of P.kuhlii is an annual cycle .It happens only ai autumn and reaches its maximum at October and November.
The sexual cycle of the male is usually accompanied with morphological and histological changes concerning their reproductive organs. Particularly the obvious gradual increase in size and weight of testes and epididymis which is described or attributed to the continuous process of spermatogenesis in seminiferous tubules. Consequently the seminal fluid is stored in three regions, the head, body, and tail along the, curved epididymis canal. The study has shown that the increase in size and weight of the testis and epididymis is reflected on their histological structure. Obviously the histological siudy has shown the sequential division of different sperm cells in order to let a large number of the mature sperms to fill the cavity of the seminiferous tubules, besides expanding the fragments of epididymis canal with it's three regions, filled with seminal fluid,
An observed regression happened in the sexual cycle at the end of November, such a regression was increased at the hibernation month and the Spring of the next year. Such a regression has a great effect on the reproductive organs retain their usual state due to the cessation of
