After a long time of observation we found that the activity of the cobra was rektively weak in the spring and relatively strong in the summer.

After a long time of observation we found that the activity of the cobra was rektively weak in the spring and relatively strong in the summer. We presumed that the direction of the blood current passing the heart might be related to season. So we chose Naja naja L. (cobra) for our research. The steps taken were as follows: (1) dissecting the heart so as to understand the structure of the heart. (2) measuring the pressure of oxygen (Po2) in the left and the right aortic arches the pulraonory artery and the vena caca pasterior (near the heart) in both spring and summercobras. (3) making ligation of 1/3 of the dorsal aorta and then determining the Po2 in the left and right aortic arches the pulmonary artery and meanwhile, we studied the change of the direction of blood current passing the heart when the systematic circulation increased. Before drawing blood, we fixed the unanesthetized cobra, exposed the heart and the heart-connecting vessels, punctured one of the vessels for getting some blood sample and had its Po2 determined with the Blood-Micro-System (Denmark). All the procedure had to be completed in 3 minute.The heart consists of two auricles and a ventride, which is divided into three cavities, i.e., cavum pulmonare, cavum venosum and cavam arteriosum. The cavam arteriosum is on the dorsum of the ventricle to the left. It receives the aerated blood from the left auricle, and there are no blood vessels directly connected with it. The cavum venosum is on the dorsum of ventricle to the right. It receives the non-aerated blood from the right auricle or the aerated blood from the cavum arteriosum. The left and right aortic arches open in this cavity. The cavum arteriosum and cavum venosum are seperated at the apex of the heart by an interventricular septum. But they are communicating through an interventricular canal at the base of the ventricle. The cavum pulmonare is on the ventral side of cavum arteriosum and cavum venosum. It receives blood from the cavum venosum and is directly connected with the pulmonary artery. There is a muscular ridge on the right side of the cavum pulmonare, forming a part of the boundary of the cavum pulmonary and cacum venosum.The free edge of the muscular ridge approaches the ventral wall of the ventricle, and thus forms a barrier between the cavum venosum and cavum pulmonare. But the function of the barrier is not perfect. When the pressure of the two sides of muscular ridge (cavum venosum and cavum pulmonare) is not equal, a selective shunt is produced.Each of the left and right auricles has an atrioventricular valve to the ventricle. When the auricle contracts, the blood dashes against the atrioventricular valves, pressing the valve close to the interventricular canal. A temporary vertical barrier is thus formed between the cavum venosum and cavum arteriosum. when the ventricle contracts, it moves back to the common boundary of the ventricle and auricle and prevents the blood from flowing backwards.The results of the investigation are as follows:1. In the spring, the Po2 in the right aortic arch is greater than that in the left aortic arch (table 1.) The nonaerated blood of the systematic circulation thus flows from the cavum pulmonare through the cavum venosum into the left arch, This may be called a right-to-left shunt.2. In the summer, the Po2 in the right aortic arch is similar to that in the left but is higher than that in the pulmonary artery. And, the latter is higher than that in the vena cava posterior (table 2). The aerated blood flows from the cavum venosum throught cavum pulmonary to the pulmonary artery thus making the Po2 of pulmonary artery higher than that in the vena cava posterior. This may be called a leftto-right shunt.3. After ligation on the dorsal aortic arch of the cobra in the summer, there exists no difference of Po2 among the right aortic arch, left aortic arch and the pulmonary artery (table 3). This indicates that the double circulation is imcompletely controlled. The shunt is caused by the change of the pressure on the both sides of the muscular ridge which

The hypocotyl of seedless watermelon was continually sectioned and systematically observed with the aid of paraffin section technique. Observations showed that the transformation from primary vascular bundle of the root radilly arranged in exarch tetrarch to bicollateral bundle of stem collaterally arranged in endarch tetrarch occurred in the cross section of transition region. The eight small bundles in the mesocotyl were gradually formed from right to left clockwise. Every pair of small bundles from different sources by the cotyledon trace drew close quickly and combined into four bicollateral bundles in collateral arrangement after changing the direction of differentiation position by 180 degrees. Another two small bundles were differentiated in the place where cotyledon trace of epicotyl took place. The transition region of vascular bundles of root and stem was at the hypocotyl where the contour was thicker than any other position. This part of the seedling performs more active physiological function and is more sensitive to environmental condition but weaker in resistance. It can be used as a morphological criterion for cultivation management.

借助石蜡切片技术对无籽西瓜胚轴进行连续切片和系统镜检。在根茎过渡区连续横切面上,可看到由根部四原型外始式初生木质部与初生韧皮部相间排列的维管束转变到茎部成为四原型、内始式和双韧并生排列的维管束。转化经过分叉、倒转和合并,是不同步的,从左到右沿顺时针力向逐步转变。中胚轴子叶迹发生处延伸出2个小束。根、茎维管束转换区发生在下胚轴。该区外形较粗大,生理活性较强,对外界条件变化较敏感,是瓜苗抗性最弱部位,也是组培择取外植体最合适的节段。可为瓜苗耕作管理和择取外植体提供形态学参考指标。
