More and more attention has been focused on ischemic-reperfusion injury of myocardium. The important role of free radicals (FRs) has been hypothesized in mediating the injury. To investigate the production and mechani...
In a previous study (C. M. J., 97(1984), 10: 717-724), we provided evidence that, the hepatocytes of guinea pig synthesizes collagen in situ after a prolonged period of immunization with human liver specific lipoprote...
Metorphamide (Met5-enkephalyl-Arg6-Arg7-Val8-NH2) was an endogenous opioid peptide isolated from bovine candate and human phaeochromocytoma tumour. Weber et al. synthesized the peptide and determined its binding act...
In guinea-pigs, cats and dogs, 4-R-2,2,5,5-tetracis (trifluoromethyl)-imidazoline (R =NHCH2OCOCH3, throughout this paper the term 'SIS-Ⅱ' refers to this derivate) has been shown to induce stepping movements toget...
Platelets play an important role in the process of hemostasis and blood coagulation. Recently, much attention has been focused on investigations of thromboembolic and bleeding diseases as well as pharmacological effec...
During the period of 1981--1982, on the basis of previous work, we continued the investigation of toxoplasmosis on domestic animals in Beijing area and 3 strains of Toxoplasma gondii were isolated from the local cats ...
Recently, collagen fibril formation by liver parenchymal cells has been reported.Whether hepatoeytes in situ produce collagen is not determined. The present letter reports that using light and electron microscopes, we...
It is an interesting but still unknown question that how the central nervous system generates the coordinative and pattern movements. For instance, studies concerning ramp or voluntary speed smooth movements, as well ...
It has been shown in a previous paper that gossypol could cause some effects on prostaglandins in the rat. In this paper, the mechanisms of infertility of gossypol has been further studied. We have observed its effect...
