RESUMO
In 167 cases of granulosa cell tumour (GCT) in the gerbil, Meriones unguiculatus, 42.5% (71 cases) were in the ovaries, with no evidence of macroscopic lesion. In this paper, we describe the common findings in the incipient--microscopic--type of this spontaneous ovarian tumour occurring in gerbils younger than two years of age.

This report describes the clinical and epidemiological findings of an outbreak of histoplasmosis in Brazil involving four persons of the same family, one adult and three children. Contamination by fecal material of bats in the basement of the house was found to be the most likely cause of this outbreak. None of the patients had evidence of immune deficiency. The adult died of acute respiratory distress syndrome. A more severe presentation of the disease in this patient may be partly explained by a heavier exposure to the feces of bats.

Eye weight growth was studied in 50 human fetuses aged 14 to 39 weeks after conception. The collected date was correlated with fetal maturity parameters (festational age and fetal weight) using the allometric method. Normal eye weight curves were obtained. The results indicate that eye weight growth present negative allometry. These curves may be important for the diagnosis of fetal eye malformations, and may indicate that noninvasive method such as ultrasounds can be used.

The relative growth of the cerebellum was studied in 300 human foetuses by using of the equation Y = bxk. The cerebellum weight was correlated to the cephalic perimeter and to the fetal weight. The relative growth of the cerebellum presented positive allometry (k = 3.3; k = 1.3 respectively). Masculine foetus presented greater index than feminine foetus.

The relative growth of the skull was studied in 300 human foetuses by using of the allometric equation Y = aXb. The skull growth was correlated to the crown-rump length and to the fetal weight. The relative growth of the skull presented positive allometry. Masculine foetus presented greater index than feminine foetus.

The relative growth of brain weight was studied in 23 Brazilian human fixed fetuses of known age ranging from 9th to 12th weeks post-conception using the allometric method: Y = aXb. The brain weight (grams) was correlated to the fetal parameters of growth: gestational age (weeks post-conception), cephalic perimeter (millimeters) and fetal weight (grams). The brain weight growth presented negative allometry relative to fetal age (b = 0.87) and cephalic perimeter (b = 2.46) and positive allometry relative to gestational age (b = 6.65). These data are important to compare the fetal growth after ultrasonic investigation.
