Fat tissue histological study at indocyanine green-mediated photothermal/photodynamic treatment of the skin in vivo

Histological slices of skin samples with the subcutaneous adipose tissue after photothermal/photodynamic treatment are analyzed. In the case of subcutaneous indocyanine green injection and 808-nm diode laser exposure of the rat skin site in vivo, the greatest changes in tissue condition were observed. Processes were characterized by dystrophy, necrosis, and desquamation of the epithelial cells, swelling and necrosis of the connective tissue, and widespread necrosis of the subcutaneous adipose tissue. The obtained data are useful for safe layer-by-layer dosimetry of laser illumination of ICG-stained adipose tissue for treatment of obesity and cellulite.     

Pharmacological effects of remaxol on endotoxicosis of peritonitis genesis

It is found that the drug remaxol, which possesses antioxidant and antihypoxant properties, is also highly effective in correction of metabolism disorders in the kidneys with peritoneal endotoxicosis. The high neuroprotective effect of remaxol is related to its ability to correct the lipid metabolism violated by hypoxia phenomena in tissues, to decrease peroxidation of lipids and activity of phospholipase A2, and to recover intrinsic antioxidant potential of cellular structures of the kidney.     

Molecular genetic analysis of Mycobacterium tuberculosis strains spread in different patient groups in St. Petersburg, Russia

Molecular epidemiological features of Mycobacterium tuberculosis strains among different patient groups in Russia have not been studied well. The aim of our study was to compare the genotypes of M. tuberculosis strains circulating among tuberculosis (TB) patients from different groups: homeless, human immunodeficiency virus (HIV)-infected, prisoners, and the general population of St. Petersburg citizens. One hundred and forty-two M. tuberculosis complex isolates from different TB patient groups were studied using the spacer oligonucleotide typing (spoligotyping) method. The majority of the studied M. tuberculosis isolates in all groups belonged to the Beijing family (55% among homeless; 77% among HIV-infected; 60% among the general population; 81% among prisoners). There were no significant differences in the Beijing family prevalence among homeless patients, HIV/TB co-infected patients, and the general population of TB patients. The lowest genetic diversity of the pathogen was detected among imprisoned patients. The results of our study demonstrate that M. tuberculosis strains circulating among patients from high-risk groups are also spread among the general population of St. Petersburg citizens.     

Clinico-morphological characteristics of pulmonary mycobacteriosis

According to the criteria of the American Thoracal Societypulmonary mycobacteriosis has been diagnosed at 40patients without clinically important immunosupression (MAC--35%, Mkansasii--25%, M. xenopi--20%, M. fortuitum--12.5% and M. chelonae--7.5%). 95% patients have had clinically important symptomatology with polymorphic radiologic development such as a deformation of a lung pattern and focal dissemination (75%), locus and infiltration (52.5%), cavities (42.5%), marked pneumosclerosis (60%) and bronchiectasis (17.5%). 75% patients have had some changes of the bronhial tree. As opposed to tuberculosis the morphology of mycobacteriosis is more homogeneous and includes inflammation with epithelioid giant-cell granuloma and fibrosis, pneumogenic and bronchogenic cavernous cavities, mycobacterial endobronchitis. The polymorphism of clinic-radiologic developments, a similarity of lung diseases morphology caused by nontuberculous mycobacteria makes difficulties to diagnose theirs.
