Cytological examination of smears from the sediment after centrifugation of pleural fluids was performed in 479 patients who underwent examination and treatment at our institution in 2014-2016. In 249 (52%) patients tumor cells were not detected in smears, in 230 (48%) observations a suspicion (28 observations) or a confident conclusion (202 observations) on the presence of malignant tumor cells in the exudates was cytologically expressed. In 38 cases immunocytochemical studies was additionally performed. In two observations a false-negative conclusion about the absence of tumor cells in smears was expressed. The sensitivity of the cytological study in the diagnosis of malignant pleuritis was 99.0%. Affirmative cytological conclusions on the presence of malignant pleuritis were given in 87.0% of observations, suspicious cytological responses - in 12.0% of cases. Immunocytochemical studies significantly expanded the possibilities of cytological research and were of great importance in the diagnosis of metastases of tumors of unknown primary localization.

SUMMARY Cadmium chloride, in a single subcutaneous injection, can destroy spermatogenic and interstitial cells in the rat testis (Pařízek, 1957) and produce changes in the pituitary. The interstitial tissue is restored by ingrowths from the tunica and full androgen secretion returns before there is any regeneration of germinal epithelium. A cytological study has been made of the peripheral and central pituitary gonadotrophs; the latter revert almost to normal as the interstitial tissue regenerates, whereas the former retain characteristic castration features, unless there is also regeneration of the germinal epithelium. This seems to indicate that in the normal testis there is a hormone contribution from the seminiferous tubules as well as from the interstitial cells. The long-term effects of cadmium on the testis depend on the dose. Early stages of tubule restoration have been studied, but after administration of 0·9 mg., actual proliferation of the germinal epithelium was rarely found—only in four out of twenty rats, 113 or 142 days after injection.
