    The afferent and efferent arterial branches of the maxillary rete were investigated in 4 lion (Panthera s. Felis leo) heads preserved in the author's department. The heads were injected with acryl plastic via the common carotid arteries to make corrosion casts of the carotid system, and examined from the standpoint of comparative anatomy. The following afferent arterial branches were observed. Medial retial branches from the maxillary artery, anterior retial branches from the anterior deep temporal artery and intraretial branches of the maxillary artery passing in the rete. The rete was constructed from the following arterial resources: Most of the lateral and inferior surfaces of the rete and deep part of the maxillary nerve tunnel from the intraretial branches; the posterior surface and posterior part of the lateral surface from the medial retial branches, and the anterosuperior part of the lateral surface from the anterior retial branches. Eight efferent arterial branches were observed. The external ethmoidal, lacrimal, interretial and anastomotic arteries, the extraocular muscular, meningeal and temporal muscular branches and the communicating branch with the external ethmoidal artery. The anastomotic artery was always well developed and played the role of the main supply route to the brain instead of the obliterated internal carotid artery as observed in the cat. Unlike that of the cat, however, the maxillary artery of the lion always passed lateral to the pterygoideus lateralis muscle, and the lateral part of the rete was not constructed because there were no lateral retial branches such as those observed in the cat.

    Venous drainage of the thoracic esophagus toward the pulmonary vein (PV) was investigated in 52 human specimens in which the veins around the esophagus were clearly observed owing to venous blood retention after injection of 10 L of formol solution into the femoral artery. Below the level of the tracheal bifurcation,43 cases (right,21; left,22) of venous drainage toward the PV were observed in 29 of the 52 specimens examined (55.8%). The direct drainage to the PV was observed mainly on the left side (19 of the 22 cases). In contrast, drainage via the bronchial vein toward the PV existed mainly on the right side (18 of the 21 cases). These drainage routes merged into the tributaries of the inferior PV, such as the inferior or superior basal vein. The draining veins often communicated with the azygos vein system on the right side (10 of the 21 cases). The veins passed through the pulmonary ligament, and also often along the vagus nerve or the bronchial artery. No venous valves were found during the course of direct drainage from the esophagus to the PV. Venous drainage toward the PV was considered to be one of the main drainage routes from the thoracic esophagus.

    The anatomical relationship between the saphenous veins and cutaneous nerves was investigated in 148 lower limbs of 74 cadavers in order to re-examine the stripping technique for treatment of varicose veins. The great saphenous vein frequently ran intimately along the saphenous nerve (59.5% in the middle third and 83.1% in the lower third of the leg) in the leg region. More than half of the latter cases showed an adhesive relationship in which the perineurium of the saphenous nerve was seen histologically to be attached to the adventitia of the vein. Moreover, in the thigh region as well, the great saphenous vein had an intimate relationship with the cutaneous nerves of various origin. In contrast, the small saphenous vein was often located close to the cutaneous nerves of the calf like the sural nerve. However, the adhesive relation between the small saphenous vein and nerves was rarely observed, in contrast to the case of the great saphenous vein.
    From these results, the anatomical relationship between the superficial vein and nerve in the lower limb were characterized according to each part of the lower limb. Based on our observations, limited extraction of the vein was recommended to reduce the risk of nerve injury during the stripping operation.

    Ultrastructure and microvascular pattern of the parotid duct (main excretory duct) in the cat were investigated by TEM and SEM. The duct was lined by a pseudostratified epithelium which was surrounded by a double-layered vascular sheath. Three kinds of principal cells were observed in this epithelium - tall columnar, light and basal cells. The tall columnar cells did not bear basement membrane specialization (infoldings) but well-developed lateral interdigitations. Microvilli were present on their luminal surface. Basal infoldings and lateral interdigitations did not develop in the light cells. Basal cells were located on the basement membrane of the epithelium. The basal surface of the duct epithelium was studded with half-desmosomes. The external sheath of the double-layered vascular sheath was composed of arterioles and venules, and the inner sheath was formed by a capillary network immediately beneath the epithelium. Meshes of the capillary network in the collecting ducts and the region of origin appeared round and in the superficial and deep regions became elongated along the duct axis. It can be concluded that the parotid duct in the cat not only transports the saliva into the oral cavity, but also actively builds up the primary saliva to the final saliva, owing to absorptive and secretory functions which were made by an important contribution of the double-layered vascular sheath surrounding the whole length of the duct.

    The high iron diamine (HID) staining procedure was combined with alcian blue pH 2.5 (AB2.5) and periodic acid-Schiff (PAS) methods for the simultaneous demonstration of carbohydrates containing sulfate esters, carboxyl groups and oxidizable vicinal diols, whereas it was sequentially employed with PAS alone to differentiate sulfate esters from oxidizable vicinal diols. A variety of rat tissues and the epidermis of four fish species were utilized to test the specificity or selectivity of these methods. The HID-AB2.5-PAS sequence largely coloured carbohydrates containing sulfate esters, carboxyl groups and oxidizable vicinal diols in brownish black, turquoise and magenta shades respectively. The HID-PAS sequence coloured sulfate esters brownish black and oxidizable vicinal diols magenta. On the basis of the experimental and control studies on the both staining techniques, these staining methods could be postulated to represent efficient and useful techniques for precise histochemical analyses and simultaneous differentiations of a variety of carbohydrates in light microscopy.

    The effects of ovine prolactin (10 I. U. /100g body wt) on the ultimobranchial body and parathyroid glands were investigated in Natrix piscator for 15 days. The ultimobranchial body of the prolactin treated specimens depicts signs of increased activity whereas the parathyroid glands exhibit reduced activity.
