"Conclusively, the present study shows that toremifene administration... results in significant improvements of all three main semen parameters -- namely sperm count, motility and morphology -- mediated by increased gonadotropin secretion and possibly a direct beneficial effect of toremifene on the testes," researcher Dr. Anargyros Kourtis told Reuters Health.

研究人员Anargyros Kourtis博士告诉路透社，目前的研究表明，使用托瑞米芬后，在促性腺激素分泌增加以及托瑞米芬对睾丸可能产生直接的有益作用的介导下，三个主要的精液参数，即精子计数、精子活力和精子形态都可以得到显著改善。

Pleomorphic adenoma is the most common gland tumor of parotid origin, accounting for 60 to 70%. This kind of tumor usually presents as a slow-growing painless mass anteroinferior to the ear. The diagnosis is based on physical examination, image studying and even fine needle aspiration biopsy. The optimal method of treatment of such tumors is local excision or paroidectomy in which the entire capsule is totally dissected off but the facial nerve is spared. Diagnosis and treatment planning are focused on preventing tumor recurrence and consequent malignant transformation.

腮腺之多形性腺瘤乃是唾液腺最常见的肿瘤，约占所有唾液腺良性肿瘤的百分之六十至七十，这类的肿瘤在临床上的表现常是耳下缓慢增生的无痛性肿块，临床上诊断的依据必须配合临床检查、电脑断层扫描、磁振造影及细针抽取切片的病理检查方可得知，其治疗方式主要是对肿瘤进行局部切除手术或腮腺的切除手术，手术中颜面神经需小心保留，但须将肿瘤的外膜部分切除乾净，诊断及治疗计画著重在预防肿瘤复发及肿瘤产生恶性转变。

The results obtained are as follows:(1) injection of 50, 100, and 200 nmol/kg adenosine into the renal artery increased the renal afferent nerve activity in a dose-dependent manner with unchanged arterial pressure;(2) pretreatment with 8-cyclopenthl -1,3-dipropylxanthine (DPCPX, 160 nmol/kg), an adenosine A1 receptor antagonist, partly abolished the effect of adenosine; and (3) pretreatment with a nitric oxide synthase inhibitor N w-nitro- L -arginine methylester (L -NAME, 0.1 mmol/kg) significantly enhanced the ARNA response to adenosine.

结果表明：(1)肾动脉内注射50， 100和200 nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX (160 nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂 L -NAME(0.1 mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。

Experimental observation on the antiHCG and early pregnancy terminating effects of arnebia euchroma.

紫草抗人绒毛膜促性腺激素及抗早孕作用的实验观察。

The effect of cadmium on the female gonad was shown to have the extrous cycle delayed and the proportion of atresic follicle increased.

镉的雌性性腺生殖毒性可表现为动情周期的明显延长，卵巢细胞生长发育过程的明显障碍。

Methods: A dual-chamber culture system was prepared. Porcine ovarian follicles were divided into healthy and atretic groups. Granulosa and thecal cells were isolated, and cultured with gonadotropin in the dual-chamber system. After 48 hours, angiotensin II, renin activity, estrodiol(E2), progesterone and testosterone in the media were determined by radioimmunoassay.

制备人胎盘羊膜双池培养系统，分离了猪卵巢颗粒细胞和卵泡膜细胞，并分为健康和闭锁两组，在促性腺激素刺激下协同培养。48 h后应用放射免疫测定法测定两种细胞培养液中的血管紧张素II、肾素活性、雌二醇(E2)、孕酮以及睾酮水平。

While testing on mRNA transcripts of either SCY2 or scygonadin,respectively in bacterially challenged mud crab,it was found that there was no significant change of SCY2 and scygonadin mRNA abundance in all of the tested tissues,suggesting that bacterial infection can not induce the transcription of both SCY2 and scygonadin genes.

检测细菌感染条件下锯缘青蟹各组织SCY2及Scygonadin表达情况，发现在感染后48 h内，SCY2和Scygonadin mRNA在性腺组织中的表达水平均无明显变化，说明外部细菌感染不是SCY2的直接诱导表达因素。

OBJECTIVE To observe the clinical effects of cardioplegia with adenosine in open heart surgery.

Human chorionic gonadotropin is a kind of glycoprotein which is synthesized by placenta tissue and chorionepithelioma. However, it has recently been found that HCG expressed in many non - germinal tumors, and was closely related with the differentiation, infiltration and metastasis of tumors.

人绒毛膜促性腺激素是由胎盘组织和绒毛膜细胞癌产生的一种糖蛋白，近几年发现其可在许多非生殖性肿瘤中出现，并且与肿瘤的分化程度、浸润转移有密切关系。
