Fresh fetal liver cells in 4~5th month human feturs of gestation were selected, which were drawn by water capsule. More than 100 patients with aplastic anemia were treated by 310 fetal livers. The treatment efficiency rate reached 67%.

According to the extension of hematomas there were five types shown on CT: type Ⅰ (17 cases ), the mass was located in the external capsule; type Ⅱ(14 cases ), the internal capsule was invaded: type Ⅲ (6 cases ). the internal capsusal and thalamus or hypothalamus were in vaded ;
WT5”BZ〗In order to study the ischemic changes of the endolymphatic sac (ES),Sixteen Guinea Pig were made into ischemic model of ES by cauterizing its supply artery and the microstructural changes were observed in different ischemic phase.
One patient died of embolic stroke 1 week after procedure,and another patient required open surgical repair because of sac aneurysm 3 months after procedure. Complete thrombosis of false lumen was achieved in twenty-two patients and partial thrombosis in one.
Preoperative screening and typing, monitoring during operation, and postoperative re-examination were executed with transthoracic echocardiography. According to the anatomic feature, the aneurysm of membranous VSD was classified into 4 types by echocardiography before operation: sac type, funnel type, fungating type and ductus type.
The pathological types were as follows: varieties of cyst in 11, angiocavemoma in 4, inflammatory pseudotumor in 2, cavernous lymphangioma in 1, cystic degeratin of liomyoma in 1, malignant lymphoma and lymphsarcoma in 6, hemangiosarcoma in 3, fibrosarcoma in 1, liomyosarcoma in 1 and malignant fibrous histiocytoma in 1. Three patients with malignancy survived for 5 years.
Its imaging characteristics mainly displayed single or multiple solid or cystic nodes. The localization rate of ultrasound was 100%,and the qualification rate of CT and MRI was more than 90% in the diagnosis of the benign splenic tumor,especially for the splenic angioma and cyst.
Most embryo sacs degenerated, and only about 4.5% of the ovules contained a normal embryo sac with an egg cell, two synergids, three antipodal, and a central cell containing two polar nuclei.
Reserve nutrients were accumulated by the musculocutaneous sac elements at the procercoid stage and, later, by the glandular and tegumental cells.
New data have been considered concerning the previously unknown intraembryonic hemopoietic organ in mammals, a region of aorta-gonad-mesonephros arising in embryogenesis simultaneously with the yolk sac.
Cytophotometric measurements of Feulgen-DNA were carried out in the nuclei of embryo sac cells of Haemanthus albiflos and Ornithogalum caudatum.
Formation of nonreduced gametes in the embryo sac was induced by low temperature (4-7°C).
Thyroglossal duct carcinoma, which is usually diagnosed postoperatively, is a rare malignant tumor arising in the thyroglossal duct cyst.
Two cases were diagnosed as thyroglossal duct cyst prior to the operation, the remaining one as dermoid cyst.
Primary thyroglossal duct carcinoma should conform to the following criteria: localization of the carcinoma to a clearly demonstrable thyroglossal duct cyst or tract; clinically or histologically confirmed absence of carcinoma of the thyroid gland.
The obligatory heterogenous tissue cyst-forming coccidia of the genus Sarcystosis are regarded as an excellent example of the specific coexistence of two organisms, i.e., the host and parasite.
Of special interest is the parasite's ability to persist in this host at the stage of tissue cyst or sarcocyst.
