The Weibel-Palade-like body were found in the cytoplasm of the growth hormone and follicullar - stellate cells of rabbit adenopypophsis. The body is surrounded by a single unit membrane. In this body, there are numerous of microtubules which can be divided into two groups depending upon their diameters.Yet, it is uncertain what the virtual function is and where the bodies come from. However, according to the experimental observations, it is suggested that the body serve as a mechanical power device which has relations with the regional distribution of the organelles. The intranuclear microtubules and intranuclear tubules were also found in the growth hormone cells. The diameters of these intranuclear microtubules range from 25 - 30 nm, and the intranuclear tubule about 78 nm. The fomer seems to be connected with the heterochromatin granules, and may be. a transitional pattern from heterochromatin to euchromatin, but their importance remain to be clarified.

The ultrastructural changes in growth hormone (GH) cells of rabbit adeno-hypophysis are determined quantitatively with stereological method after burn injury. Blood sugar levels are concurrently measured. The results show: the volume fraction of Golgi complex, mitochondria and rough endoplasmic reticulum shows a 2-phase curve after burn, and it may be divided into 3-periods stress, modulation and functional activation and recovery; the rate of maturation of secretory granules is increased; a close relation between the blood sugar and some activities of GH cell secretion after burn presents; the autocrine shows a negative feedback to the exocytosis in the control group,and a positive feedback in burned ones; the newly formed mitochondria may be originated from the new Golgi complex from the reutilization of plasma components.

Objective To evaluate the importance of the prenatal diagnosis to fetus with mild ventriculomegaly ( MVM) in pregnancy outcome and prognosis. Methods The ultrosonographic results of 51 pregnant women who were admitted to our hospital were collected in this study. In each case,a thorough evaluation of fetal anatomy was performed,karyotyping or MRI was done if needed,and follow-up was done un-til afterbirth. Results In 51 cases of lateral ventriculomegaly fetal:ultrasonography indicated there were 26 fetuses with mild ventriculomega-ly. The incidence of MVM complicated with other abnormities was 46. 0%,and that complicated with chromosome disorder was 11. 5%. Con-clusion Ultrasonography plays an important role in the detection of MVM. Chromosome analysis should be carried out for elder pregnant women when their fetuses are diagnosed as MVM and other complicating abnormities.

Objective To explore the imaging features of pediatric splenic primary solitary tumor. Methods The medical imaging appearances of 6 children with splenic primary solitary tumor conifrmed by surgery and pathology from January 2010 to August 2015 were retrospectively studied. The related literatur were reviewed. Results In 6 children, 2 children of cystic lesions, ultrasound showed anechoic mass, CT scan showed low density mass, without change after contrast, pathologically conifrmed as congenital cyst;2 children’s ultrasound showed solid echo, color Doppler ultrasound explored the blood lfow signals, contrast CT showed the lower strength around the splenic parenchyma, pathologically conifrmed as splenic lymphangioma;one child’s unltrasound showed echo mass with rich signals of blood lfow, MRI scans showed T1WI, T2WI and other signals of lumps, with little homogenity after contrast, pathologically conifrmed as splenic hamartoma;one child’s ultrasound cannot distinguish tumor boundaries, contrast CT scan showed concentric filling reinforcement, pathologically confirmed as hemangioma. Conclusion Splenic primary solitary tumor in children is rare. There are no speciifc clinical characteristics. The image ifndings can deifne the locations and help the differential diagnosis. The ifnal diagnosis depends on pathology.

Objective To evaluate the sonography features of heptaobiliary involvement of pediatric Langerhans′cell histiocytosis ( LCH) . Methods Nine pediatric patients with LCH confirmed by the clinical presentation ,biochemical tests and pathologic results of our hospital were retrospectively analyzed . Results Eight patients were seen in multi‐system LCH ,while one patient only had liver involved . All patients showed varying hepatomegaly with multiple distributed lesions in ultrasound images . According the lesion distribution features ,they could be classified into three types:central type(6/9) ,peripheral type(1/9) and diffuse type(2/9) . In ultrasonography ,they manifested as linear lesions alongside the central portal veins , multi‐nodular and randomly distributed lesions in liver parenchyma ,or both of them . Eight bile‐duct involved patients behaved with unevenly thicked bile‐duct walls ,stenosis or dilated bile‐ducts ,and even sclerosing cholangitis , some of them with cholelithiasis . Conclusions Pediatric LCH patients with heptobiliary involved are seemed mainly in multi‐system LCH ,while it is rare but possible that pathological Langerhans′cell only infringe on liver and bile‐ducts . The ultrasound imaging findings of pediatric LCH liver infiltration are with characteristic and are helpful for the early diagnosis and clinical procedure .

Objective To summarize and analyze the relationship between exposure to rabies and its prevalence in Jurong City from 2003 to 2007,and discuss further the possible solutions to it.Methods The data of people vaccinated after being biten by animals were collected,manipulatd,and analyzed,with their illness records dealt with accordingly from 2003 to 2007 in Jurong City.Results Not a single one of 21 596 cases was that of rabies with proper treatment in the last 5 years.The sex ratio was 1.47∶1.The highest probability of exposure was the preschoolers under the age of 10.The disease occurred throughout the year,with the peak in July and September.Those biten by dogs accounted for 86.85% of the exposure to rabies,and among them,people biten by domesticated animals were in the majority.Wounds by the domesticated dogs reached 74.60%.Not a single case was treated properly among the 9 rabies cases reported in the same period.Conclusions Strengthening the management of domesticated dogs,publicizing the knowledge of rabies,treating the wound properly and thoroughly,innoculation with vaccine from the very beginning and administering rabies immune globulin are the effective ways to prevent rabies.
