On solvability of the variational Dirichlet problem with nonhomogeneous boundary conditions for degenerate elli ptic operators in a bounded domain
Solvability of the variational Dirichlet problem with nonhomogeneous boundary conditions for a class of the higher order elliptic operators in a bounded domain with power degeneracy on the boundary is investigated in the article. The investigation is based on an analogue of the Garding inequality for the class of operators under consideration. Along with existence of unique solution an associate inequalities for its norm are proved.

Key words: задача Дирихле; эллиптический оператор; неоднородные граничные условия; степенное вырождение; Dirichlet problem; elliptic operator; nonhomogeneous boundary condition; power degeneracy.

Influence of the irregularity of heterointerface a temperature dependence of the threshold current and differential efficiency of heterolasers
The quantitative analysis of the influence of the irregularity of heterointerface on the threshold current and differential efficiency of heterolaser of InGaAsP has been done. Have been shows that by taking account the irregularities of heterointerfaces a temperature drop of the differential efficiency of lasers can be explain without involvement of any microscopic mechanisms.

Comparative study of the hydrogel microsphers formation from different pectin and zein with model drug
The results of microsphere formation from different HM- and LM-pectins and corn zein in presence model drug are presented. It’s show that the drug loading capacity differ among pectins used and depend on the structure and complex formation properties whether by crosslinking with bivalent metal ions or with hydrophobic zein protein. As a result a number of microspheres have been prepared from biodegradable and biocompatible naturally occurred materials for controlled drug delivery system.

Key words: пектин; зеин; микросферы; носители лекарственных препаратов; pectin; zein; microsphers; drug delivery system.

Results of Hodgkin’s lymphoma treatment in the women in the Republic of Tajikistan
The article illustrates immediate efficiency of various schemes of chemotherapy in the patients with Hodgkin’s lymphoma. Such complications as a medicinal intoxication, oppression of bone marrow sprouts, infringement of ovario-menstruation cycle, took place in the patients of active reproductive age with Hodgkin’s lymphoma. In connection with high frequency of infringement of the treatment rhythm, the unsatisfactory remote results of chemotherapy were marked.

Key words: лимфома Ходжкина; репродуктивный возраст; химиотерапия; выживаемость; Hodgkin’s lymphoma; reproductive age; chemotherapy; survival rate.

Тhe experience of using wound coating "Tachocomb" for liver echinococcosis
During the 2010 to 2012 the 13 patients with liver echinococcosis were examined. The age of patients ranged from 22-76 years. In 9 (69%) patients echinococcal cysts were located in the right lobe of the liver, the left lobe – 4 (30.7%). Depending on the size and volume of the cyst distinguished medium to 10 cm – at 7, up to 20 cm long – at 5, and a giant – over 20 cm in diameter – in 1 patient. Solitary liver cysts presented in 11 (84.6%), multiple in 2 (15.4%) patients. The diagnosis of liver echinococcosis is set on the basis of clinical, laboratory, ultrasound, x-ray, computed tomography, and laparoscopy. All 13 patients were used plate "Tachocomb": with the aim of additional hemostasys after a typical resection of the liver – in 4 cases, seam sealing biliary fistula – 9 patients.

Key words: эхинококкоз печени; жёлчные свищи; Тахокомб; минимально инвазивная эхинококкэктомия; miniassistant; echinococcosis liver; biliary fistula; Tachocomb; mini invasion surger.
