52 types of os temporale had been studied to determine antrum walls on the outside size, from face aditus to ampullae lateral semicircular canals size, antrum ceilling size, from antrum below walls to sigmoid sinus size; antrum radius:on- below, in-out of and before-behind. The understanding of anatomy detail of antrum and its interrelationship will help to avoid the misfortune surgery

Introduction: Dissecting cadavers to study Human Anatomy is an integral part of first year medical education. The aim of this study was to describe the experiences of the first year medical students during their first day of cadaver dissection. Methods: This study analyzed interviews of three first year medical students, chosen via purposive sampling, who were present during the first day of cadaver dissection in gross anatomy. Interviews were transcribed and analyzed through a Husserlian descriptive phenomenological approach. Results : Five common themes were identified: 1) fear of the unknown, 2) group dynamics, 3) sense of awe and amazement of the cadaver's body, 4) respect for the body, and 5) taming of death as a rite of passage to being a doctor. Conclusion Of the five emergent themes, taming death as a rite of passage to being a doctor is the essence of the experiences of the first year medical students during the first day of cadaver dissection.

OBJECTIVETo compare morphological characteristics of pollen of Lonicera japonica in different cultivars cultivated in Shandong and provide a basis for distinguishing different cultivars and selecting fine breeding.

METHODThe scanning electron microscope (SEM) was applied to observe and compare the outside characteristics of pollen,and the data were analyzed by SAS 9.1 software.

RESULTSome difference was found among pollen size, aperture length and the density of spine. The biggest pollen size and aperture length is Dajizhao with 61.97 microm polar axis and 61.79 microm quarter major axis and 18.03 microm aperture length,and the smallest is Honggengzi with 57.46 microm polar axis and 57.29 microm quarter major axis and 18.03 microm aperture length.

CONCLUSIONThe morphological characteristics of pollen can provide a basis for distinguishing different cultivars of L. japonica.

Materials: leaves and flowers of Stephanie glabra (Roxb) collected from Ninh Binh and Ha Noi (sample plants) through 3 flowering seasons. Methods: observations by steric microscopy (Nikon-Japan). The botanical features of Stephanie glabra: creeping stem, leaf peduncle (5-10cm), leaf nervure (11), masculine inflorescence, inflorescence pedicle has 5-6 umbels, each umbel has 8 secondary umbels, each secondary umbel has 4 third umbels, the inflorescence ended by 3 flowers with short pedicles. Masculine flower has 6 separate calixes, which were arranged as 2 circles. Ovular calix. Ovular tepal (3), gamo staminate with 6 slight yellow microsporangiums. The microsporangium changed into pill.

OBJECTIVETo provide theoretical evidences for the identification and selective breeding of different major varieties of Rehmannia glutinosa by comparing their leaf characters such as the shapes, non-glandular hairs and the size and density of stomata.

METHODThe length, width and the ratio of the length to the width of leaves were measured, and the density and length of the non-glandular hair, the density, size and density of the stomata in the epidermis were measured by scanning electron microscope.

RESULTThe results showed that there were obvious differences in length, width and the ratio of the length to the width of leaves, the density and length of the non-glandular hair, the density and size of the stomata in the epidermis.

CONCLUSIONThe morphological characters of the leaves mentioned above may serve as the identification standards of major varieties of R. glutinosa.

Study on the anatomical and morphological features of Acanthopanax gracilistylus W.W. Smith and A.trifoliatus (L.) Merr. collected in Sa Pa district, Lao Cai province and Pho Bang district, Ha Giang province. Results: scientific name of 2 collected samples had been identified as Acanthopanax gracilistylus W.W. Smith and Acanthopanax trifoliatus var. setosus Li. The anatomical features of these 2 species were detailed described. The morphological features of leaf, stem and root of A.trifoliatus (L.) Merr. collected in Sa Pa and Pho Bang was detailed described firstly. The morphological characteristics of 2 species were similar

The ectopic pancreas is rare abnormal anatomy. This paper introduced 4 cases of the ectopic pancreas, which had occurred when patients were fetuses. The ectopic pancreas mainly focused in the upper digestive tract. In generally, there were no symptoms. If have, the symptoms were various which depended on the position and size such as digestive bleeding, ileus, intussuseption and pancreatic pathology such as acute or chronic pancreatitis. The ectopic pancreas usually was diagnosed before operation. It should remove the ectopic pancreas if it is the pathogen.
