Vulvovaginites: estudo das variaçoes de pH vaginal e microflora associada / Vulvovaginitis: vaginal pH changes and associated microflora

PURPOSE: To establish a correlation between pH vaginal and the microflora associated in carriers of vulvovaginites. METHODS: In the present study, the cytopathological examination and the vaginal flow in a group of 65 sexually active women had been carried through, 20 and 72 years, taken care of in the Laboratório de Citologia Clínica do Departamento de Análises Clínicas e Toxicológicas da Universidade Federal do Rio Grande do Norte, for determination of microorganisms in cervicovaginal sample and of pH in the vaginal flow. RESULTS: Associating pH vaginal with the presence of vulvovaginitis, it was evidenced that the Candida sp. occurred more frequently in pH 4.0, Trichomonas vaginalis in pH 6.0, Gardnerella vaginalis in pH 5.0, coconuts in pH 5.0, bacilli in pH 4.0 and cocos/bacilos in pH 6.0. It was observed that all the patients had presented at least one type of ethiological agent of vulvovaginiti and an associated microflora. CONCLUSION: The joint accomplishment of the cytological examinations and the determination of pH revealed important for directing the microflora associated with the vulvovaginiti, suggesting, of this form, that pH vaginal plays preponderant role how much to the presence of the infectious agents in the vaginal ecosystem.

Correlaçäo entre contagens de células somáticas determinadas no "Somacount 300" utilizando-se os detergentes RBS 35 e Extram MA 01 alcalino / Correlation between milk somatic cell counting of samples prepared with two detergents, and analyzed by the Somacount

The objective of this work was to compare the values of milk somatic cell counts (SCC) using the Somacount 300, and two detergents for sample preparation. the equipment was calibrated using the detergent RBS 35. Forty independent milk samples were analyzed. Each sample was randomly divided into two subsamples, and each subsample was analyzed after preparation with either RBS 35 or Extram MA 01 Alkaline detergents. the correlation coefficient between the two methods was high (0.998). This finding suggests the possibility of substitution of RBS 35 for an economical alternative
