Spontaneous death of certain classes of germ cells has been shown to be a constant feature of normal spermatogenesis in a variety of mammalian species, including the human. Recent studies on various… (More)
Calcium-ion uptake by normal and leukemia lymphocytes increased during a 30-min exposure to a 13.6 Hz, sinusoidal magnetic field at 20 microT peak. The time-varying field was horizontal and parallel… (More)
Forty dogs were divided randomly into four groups. The portal circulation was reduced to 50%-60% for one hour by partially occluding the superior mesenteric artery (SMA) for the purpose of… (More)
Testosterone undecanoate (TU) provides testosterone (T) replacement for hypogonadal men when administered orally but requires multiple doses per day and produces widely variable serum T levels. We… (More)
This is a pilot dose-finding study of spermatogenic suppression using testosterone undecanoate (TU) injections alone in normal Chinese men. Thirty-two healthy men were recruited. Volunteers underwent… (More)
The rabbit has been used to model the potential effects of in utero exposure to cocaine on fetal and postnatal development. Special advantages of this animal model include the fact that cocaine can… (More)
AIM
To study the effect of testosterone undecanoate (TU) injection on spermatogenesis in rats.
METHODS
Twenty adult SD rats received vehicle or TU (8 mg/kg, 19 mg/kg or 625 mg/kg) injection, im,… (More)
Sodium pentachlorophenate (Na-PCP) has been used in China for years as an molluscacide to kill oncomelania, which is an intermediate host of Schistosome. To evaluate the effects of its long-term… (More)
Since 1979 several derivatives of artemisinin have been synthesized and studied in China. Artemisinin suppositories, artesunate (oral or parenteral), intramuscular artemether and dihydroartemisinin… (More)
Spermatogenesis in Asian men appears to be more susceptible to suppression by steroidal contraceptives administered in clinical trials than spermatogenesis in Caucasian men. The objective of this… (More)
