PURPOSE This study evaluated the spontaneous healing capacity of surgically produced cranial defects in rabbits with different healing periods in order to determine the critical size defect (CSD) of the rabbit cranium. METHODS Thirty-two New Zealand white rabbits were used in this study. Defects of three sizes (6, 8, and 11 mm) were created in each of 16 randomly selected rabbits, and 15-mm d...

We recently demonstrated sexual dimorphism in the S3 segment of the ICR mouse kidney, as differences in periodic acid Schiff (PAS) staining on the brush border and the number and size of PAS-positive granules. However, whether these sex dependent features in the S3 segment of the mouse kidney occur only in the ICR strain or are a general feature also observed in other strains is unclear. In the...

Boron is a chemical element widely used in many industrial activities. Exposure to it affects many organs in mammals, mainly reproductive male organs. This work evaluates boron effect in testis. For this purpose, 12mg Boron/L of drinking water, equivalent to Arica tap water, was given for 42 days to 85 days old CF1 male mice (experimental group). Another group (control group) drunk tap water of...

Dimitrov, D. S., 2014. the lachrymal gland in manchurian and Pharaoh Japanese quails – A histometrical investigation. Bulg. J. Agric. Sci., 20: 1498-1501 the study was carried out on 40 sexually mature and clinically healthy Japanese quails (20 females and 20 males) from the stock hybrids manchurian Golden and Pharaoh. After weighing and determination of metric parameters, 80 lachrymal glands w...

The effect of antigenic stimulation (paratyphoid vaccine) on high endothelial venules (HEVs) of rat cervical lymph nodes was studied using conventional histological and histometrical techniques. The sequential changes of some morphometric parameters (lymph node weight, HEV diameters) after the antigenic stimulation were studied in rat cervical lymph nodes over a period of five days with daily m...

This research was carried out to define the morphological features of infundibulum and magnum in turkey and pigeon. For this purpose, a total of 10 adult healthy turkey (No=5) and pigeon (No= 5) were used. After dissecting, infundibulum and magnum of each specimen was separated by incision and fixed in 10% buffered formalin. For histological studies, after tissue preparation and staining with H...

Gall inducing insects most frequently oviposit in young tissues because these tissues have higher metabolism and potential for differentiation. However, these insects may also successfully establish in mature tissues as was observed in the super-host Copaifera langsdorffii. Among C. langsdorffii gall morphotypes, one of the most common is a midrib gall induced by an undescribed species of Cecid...
