This paper describes a modified method for the saturation assay of 3', 5'-cyclic AMP. After separation of bound cAMP from free cAMP by means of an acetate-cellulose filter, the filter on which the bound radioactive moieties were retarded was placed in a scintillation vial containing 5 ml scintillation fluid and counted directly. The sensitivity is of the order of a few picomoles.Conditions affecting the assay and counting have also been studied and discussed.

Using Southern Blot method we studied the presence and state of HBV DNA in sperm samples obtained from 13 patients with HBV chronic infection ( 8 chronic persistent hepatitis B, 5 chronic active hepatitis B ) and 2 normal controls, The half of the extraction was digested with restriction enzyme HindⅢ,the two halves were gelelcctropharesed and transferred to the cellulose filters, The filters were then molecular-hybridized with a probe of ~( 32)P-HBV-DNA Presence of HBV DNA was detected in four sample of spermatozoa, three free forms and one integrated form were identified.The results indicate that HBV DNA may be present in the spermatozoa,The presence of free form of HBV DNA suggests to have the . possibility of infection, the presence of integrated sequences in spermatozoa suggests the possibility of vertical transmission by generative cells.

用Southern Blot方法,我们研究了13份慢性HBV感染患者(8份慢迁旰,5份慢活肝)和2份对照精液标本中HBV DNA存在状况。提取物一半用限制酶HindⅢ消化,各行琼脂电泳,转移到纤维膜上,然后用~(32)P—HBV—DNA探针分子杂交。在4份精子內检出HBV DNA,3份为游离形式,1份为整合形式。结果表明HBV DNA可以存在精于内,游离状态HBV DNA提示有传染性、整合序列HBV DNA的存在提示有通过生殖细胞遗传的可能。
