Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.

Results: The renal perfusion was increased in diabetes group after the injection of alloxan. The PSI, AUC and ascending slope rate of the curve of the time-intensity curve were increased in 1w and 2w with decreased of HPT; the pathological examination exhibited glomeruli hypertrophy and no thickening of basal lamina. The PSI and AUC in 4w and 6w were more than that of control group; the PIT and ascending slope rate of the curve got closed to normal in 4w and 6w; the intercapillary cells increased. The speed of ascending slope rate of the curve in 8w, 10w and 12w was slower, shown as PIT and HPT delayed; the pathological examination showned increasing of mesangial cell, hyperplasia of mesangial matrix and thickening of basal lamina, followed with obliteration of partial micrangium, glomerular sclerosis and reduce of PSI in 12w.

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

basal lamina：基板

橋粒存在于上皮組織中,主要是維持上皮結(jié)構(gòu)的完整性,半橋粒位于上皮細胞的底面,作用是把上皮細胞與其下方的基板(basal lamina)連接在一起. 橋粒、半橋粒及上皮基底膜對維持上皮組織結(jié)構(gòu)的穩(wěn)定性及分子屏障功能具有重要意義.

basal lamina：基膜

層粘連蛋白主要存在于基膜(basal lamina)結(jié)構(gòu)中,是基膜所特有的非膠原糖蛋白, 相對分子質(zhì)量為820kDa, 含13-15%的糖,有三個亞單位, 即重鏈(α鏈, 400kDa)和β1(215kDa)欧美一级高清a视频永久免费、β2(205kDa)兩條輕鏈.
