Preliminary Investigation On Effects Of Burantashi Extract On Liver Enzymes Of Aibino Male And Female Whistar Rats


This work was carried out to investigate the effects of Burantashi extract on liver enzymes of albino male and female whistar rats. Burantashi is a popular seasoning agent to barbecued meat (suya) in Nigeria,mostly found in the northern part of the Nigeria. Liver Enzymes are those enzymes that plays important role in the liver both in function and regulation. Erectile dysfunction (ED) is defined as the consistent or recurrent inability of a man to attain or maintain penile erection, sufficient for sexual activity (2nd) International consultation on sexual Dysfunction Paris, June 28th July 1st, 2003). Following the discovery and introduction of Burantashi research on the mechanism underlying penile erection, has had an enormous boost and many preclinical and clinical papers have been published in the last five years on the peripheral regulation of, and the mediators involved in human penile erection. The most widely accepted risk factors for ED are discussed. The research is focused on human data and the safety and effectiveness of Burantasni Stem as a phosphodiesterase -5- Inhibitors (PDE-5) used to treat Erectile Dysfunctions.

Chapter One


Physiology Of Erection

Penile Erection involves an integration of complex physiological processes involving the central nervous system, peripheral nervous system, hormonal and vascular systems. Any abnormality involving these systems whether from medications or disease has a significant impact on the ability to develop and sustain erection; ejaculate and experience orgasm. (Laumann et al., 1999).
The physiological process of erection begins in the brain and involves the nervous and vascular system. The chemicals that initiate erection are neurotransmitters present in the brain. Any kind of stimulation physical or psychological, causes nerves to send message to the vascular system which result in significant blood flow to the penis. Two arteries in the penis supply blood to erectile tissues and the corpora cavernous which become engorged and expand as a result of increased blood flow and pressures. Because blood must stay in the penis to maintain rigidity. An erectile tissue is enclosed by tunicae, which is fibrous elastic sheathes cinch which prevents blood leaving he penis during electron. When muscle in the penis contract to stop the inflow of blood and open out flow channels and an electron is reserved.

Hormonal Involvement In Erection

Oestrogen / Progesterone:

(These are female hormones that cause clitoral erection. If the body has two much oestrogen and or too little testost erone, she ca n get very wet but can not erect her clitoral and G-spot. ( Haimen et al., 2002). Estrogen tends to increase the size of the bread, labia minors (inner lips) and clitoral hood, but shrinks the glans clitoris into the clitoral hood making it invisible. It also increases the thickness of the vaginal lining making the G-spot inaccessible. The mechanism of the clitoral and G-spot erection is the same as that of the penis. It is driven by the parasympathetic sexual nerve (The neurotransmitter acetylcholine) through the neurotransmitter. Nitric oxide and the erection dilator cGMP, which is continuously powered by the burning of testosterone without a testosterone burst and burning. She cannot pop the glans Clitoris and G-spot out. If she is on birth control pills there is a chance that her body is over flooded by estrogens and low progesterone. Over loaded liver cannot produce sufficient essential enzymes to synthesize sufficient NO, cGMP and testosterone to support the clitoral and G-spot erection infact excessive estrogen or progesterone in the body will shrink the penis, clitoral and G-spot, but likely increase the breast size (under the excessive estrogen action).
