[A new approach in the surgery of prostatic sclerosis].

The authors propose a new technique of prostatic sclerosis surgery which makes use of a transperineal approach and is based on the principles underlying surgical management of posterior urethra high strictures with establishment of a cystourethral shunt. Good results obtained in 17 patients with prostatic sclerosis allow the authors to consider the above procedure as an alternative to transvesicular prostatectomy according to V. S.

[The validation of applying a longitudinal suture to the bladder neck in bladder-urethra anastomosis].

The author gives theoretical validation for placing a longitudinal suture instead of a cross suture on the bladder cervix in cystourethral shunting. Cross sutures preclude deviations in the shunt region thus reducing probability of urethral stricture recurrences. For conduction of the suturing a special device "needle bougie" has been developed.

Correlation between cholesterol content in circulating immune complexes and atherogenic properties of CHD patients' serum manifested in cell culture.

Blood serum of most patients with coronary heart disease (CHD) caused a 2-5-fold increase in the total cholesterol content of smooth muscle cells cultured from unaffected human aortic intima, i.e. possessed an atherogenic potential manifested in culture.

Peritoneal macrophages: a model for detecting atherogenic potential in patients' blood serum.

Human and mouse peritoneal macrophages cultured in the presence of the blood serum of patients with documented coronary heart disease showed a 2- to 3-fold rise in levels of intracellular cholesterol ester and a 1.5- to 2-fold increase in those of free cholesterol and triglycerides. This effect was observed in 83% of cases, whereas the serum of healthy subjects induced the accumulation of lipids in macrophages only in 28% of cases.
