Data are presented to demonstrate that the effects of gonadectomy on body weight and food consumption differ in male and female rats. The findings are related to the authors' report of sex differences in the effects of ventromedial hypothalamic damage. A review of the literature on the relationship of the gonads to body weight in different species is presented.

The relationship of increasing obesity to storage of neutral fat in the mesentery was investigated in 48 albino rats. Calculated as grams per 100 g nonlipid dry weight, levels of mesenteric neutral fat were positively correlated with levels of mesenteric free cholesterol, phospholipid, and water, the correlation coefficient for water being higher in male than in female rats. These results suggest that storage of neutral fat is an active physiologic function of mesentery. On the other hand, the relative amount of body neutral fat which is stored in the mesentery became less as the animals became more obese. This indicates that in obese rats, some tissue other than mesentery is storing neutral fat at a rate greater than occurs in the mesenteric fat depots.

Pancreatic tissue (original and recut sections) from Fischer 344 rats fed 2,6-dichloro-p-phenylenediamine in a chronic (2-year) carcinogenesis bioassay was evaluated for presence of pancreatic hepatocytes (PH) by light microscopy. PH were found in dose groups as follows: males–0 ppm (controls)–0/50 (0%), 1,000 ppm–4/50 (8%), 2,000 ppm–9/50 (18%); females-0 ppm (controls)–1/50 (2%), 2,000 ppm–15/50 (30%), 6,000 ppm–15/49 (31%). This represented a significant dose-related increased incidence of PH in 2,000-ppm males, and 2,000- and 6,000-ppm females. A statistically significant increase ( p < 0.01) in pancreatic acinar atrophy and fibrosis was also seen in treated female rats, but the relationship of these lesions to the PH is unclear.

Good quantity and quality of bones are keys to the success of prosthodontic treatment. The quantity of bones is showed by the height of mandibular residual ridge, whereas the quality of bones is indicated by the bone density.The aim of this study is to investigate the relationship between the age, the bone density, and the height of the mandibular residual ridge. The observation is carried out to six edentulous menopausal women. The height of mandibular residual ridge and the mandibular bone density are measured by using CBCT-3D (Cone Beam Computed Tomography-3 Dimension). Pearson analysis of bivariate correlation is used to determine the relation between variables. As a result, there is a strong correlation between the increased of the age and the decrease of mandibular bone density (r=-0.922 with α=0.009). The study also shows a significant correlation between the decrease of the height of mandibular residual ridge and the decrease of the mandibular bone density (r=0.815 with α=0.048) and between the decrease of the height of mandibular residual ridge and the increase of the age (r=-0.89 with α=0.017).To summarize, the decrease of the height of mandibular residual ridge in this study correlates with the decrease of the mandibular bone density and the age.

ABSTRAK Ekosistem padang lamun di Perairan Bandengan Jepara penting bagi biota akuatik khususnya epifauna. Kerapatan lamunakan mempengaruhi bahan organik yang digunakan oleh epifauna, selain itu kerapatan lamun juga dapat mengendapkan bahan organik yang akan mempengaruhi kelimpahan epifauna. Penelitian dilakukan pada bulan Maret 2016 di Perairan Bandengan yang bertujuan untuk mengetahui hubungan antara kelimpahan epifauna dengan kerapatan lamun yang berbeda di Perairan Bandengan Jepara serta hubungan antara kandungan bahan organik dengan tingkat kerapatan lamun di Perairan Bandengan Jepara. Metode penelitian yang digunakan yaitu pendekatan survei dengan metode sampling yaitu Purposive Random sampling. Hasil penelitian menunjukkan terdapat 1 jenis lamun yang ditemukan di Pantai Bandengan  yaitu Thalassia sp. dengan kerapatan pada stasiun jarang (A) 178 ind/m2, stasiun padat (B) 368 ind/m2. Kelimpahan epifauna di kerapatan jarang dan padat di Perairan bandengan 140 ind/3m2, dan 91 ind/3m2. Rerata kandungan bahan organik sedimen pada kerapatan jarang, dan padat berturut-turut adalah 12.86% dan 76.85%.Berdasarkan hasil uji regresi menunjukkan antara kelimpahan epifauna dengan tingkat kerapatan lamun menunjukkan hubungan tidak searah, setiap kenaikkan kerapatan lamun tidak diikuti oleh kenaikkan kelimpahan epifauna, serta tingkat kerapatan lamun dengan bahan organik terdapat korelasi yang kuat, semakin tinggi tingkat kerapatan lamun akan diikuti oleh bahan organik.  Kata Kunci; Perairan Bandengan; Kerapatan Lamun; Kelimpahan Epifauna; Bahan Organik.  ABSTRACT Seagrass ecosystem in Bandengan coastal Jepara is important for epifauna. Different seagrass density will affect levels of organic matter used epifauna, in addition the density of seagrass can also precipitate organic particles which affect the abundance of epifauna. This research was conducted on March 2016. The aimed of this research was to determine the relationship of epifauna’s abundance to density seagrass and the relationship of organic matter to the density of seagrass. This research used survey method and random sampling technique. Samples were taken from three different station there are (A) sparse density, and (B) dense density. Sample epifauna were taken once a week for three time. The results showed only 1 type of seagrass found in Bandengan coastal Jepara that is Thalassia sp. With density on sparse station (A) 178ind/m2, dense station 368 ind/m2. The abundance of epifauna on station sparse (A) 140 ind/3m2, dense station (B) 91 ind/3m2, The highest abundance Sconsia sp 52 ind/m2 dan 28 ind/m2 and Cerithium sp 34 ind/m2 dan 19 ind/m2Organic material content of sedimen on density was sparse and dense was 5.71%, 9.81%. Based on the result of the correlation show that between the abundance of epifauna with seagrass density level there is a relation undirectional, density of seagrass will not increase accordingly to the abundance of epifauna, as well as to the content of organic matter. There is a close correlation that higher of density of seagrass will be followed by organic matter. Key Word; Coastal of Bandengan; Seagrass Beds Density; Abundance of Epifauna; Organic matter

Introduction: Osteopenia is a condition which means the bone mineral density (BMD/BoneMineral Density) is lower than the normal peak BMD but not low enough to be classified as osteoporosis.Risk factors that can lead to osteopenia are smoking, drinking softdrinks, less activity, dieting,rarely affected sun and drinking alcohol. This study aimed to identify the risk factors of asteopenia onadolesences. Method: The study design used descriptive. The sample used was a high school studentMagetan total of 100 respondents were collected by random sampling. Data were collected withquestionniare and analyzed with procentage. Result: From the results of a study of 100 respondents wasobtained from less activity factors 5 respondents (5%), rarely exposed to sunlight obtained 32 respondents(32%), dieting factor obtained 34 respondents (34%) smoke got 49 respondents (49%), drinkalcohol obtained 18 respondents (18%),and drink softdrink obtained 40 respondents (40%) at risk forosteopenia. Discussion: From the results it can be concluded that smoking is the highest risk factor inthe incidence of osteopenia among adolescent. Nicotine contained in cigarettes can reduce absobsicalcium in the bones and cause a decrease in bone density. For any subsequent researchers are expectedto conduct research about the relationship of smoking with risk factors for adolescent osteopenia .
