Habbatus sauda (Nigella sativa) is a plant commonly used as herbal medicine for treatment of diseases while nicotine is an
addictive chemical that is present in cigarettes. The study was conducted to observe effects of habbatus sauda oil on histological
features of nicotine treated male rats’ seminal vesicles and prostate glands. Rats were divided into five groups: corn oil (COhabbatus
sauda control), habbatus sauda (HS), saline (S-nicotine control), nicotine (N) and nicotine–habbatus sauda (N-HS).
The CO and HS groups were force–fed with 0.1ml/100g and 6µl/100g, respectively. The S and N groups were intramuscularly
(i.m.) injected with 0.1ml/100g and 5.0mg/100g, respectively. The N-HS group was treated with the same dosage as the N and
HS groups. The treatment was conducted for 100 days. The prostate glands and seminal vesicles of animals in the N group
showed reduction in the epithelial height of the mucosal linings compared to that of in the S, CO, HS and N-HS groups.
Moreover, there was also less acidophilic secretion found in the glands of the animals in N group compared to the other 4
groups. However, the histology of the prostate glands and seminal vesicles in the N-HS group was noted to be similar to that of
in the control (S and CO) groups. Hence, this suggested that administration of habbatus sauda oil could lead to an improvement
in histology and function of both prostate glands and seminal vesicles in the nicotine treated rats.
