PURPOSE:To verify existance of a-,~-,and 3'-protein kinase C(PKC)subspecies and
their localization in rabbit retina. METHODS: Using an immunohistoehemical technique with mono-
elonal antibodies against PKC isozymes- I (a),-I[ (13),and -~[ (Y) to characterize the distribution of
PKC in rabbit retina. RESULTS:There is a positive immunostaining for a-,13-,and ~-PKC in rabbit
retina. The immunoreactivity of a-PKC was observed mainly in the bipolar cells of inner nuclear layer
and the outer segments of photorecptors. The positive immunostaining of 13-PKC could be seen in the
ganglion cells,inner plexiform layer,inner nuclear layer,and the outer segments of photoreceptors. A
diffuse and weak staining of Y-PKC is recognized in the ganglion cell layer,inner plexifrom layer,inner
nuclear layer, and the outer segments of photoreceptors. CONCLUSION:The protein kinase C sub-
speeies-a,-~,and-'Y are present in retina which is a part of the central nervous system

脉络膜黑色素瘤是成年人最常见的原发性眼内恶性肿瘤,是致死的最主要原发性眼内疾病。近20来,以美国及加拿大学者为主要成员的眼部黑色素瘤协作组,对该肿瘤的治疗方式的选择进行了大量的临床研究,有许多新的认识。

核因子-kappa;B(nuclear factor-kappa B, NF-kappa;B)是一个多功能核转录因子,具有广泛的生物学活性,直接参与机体对炎症和免疫反应的调控,在细胞凋亡中起到一种稳定作用,并参与新生血管的形成。NF-kappa;B在炎症性视网膜疾病、视网膜光损伤、视网膜新生血管形成等的病理过程中起关键作用。对NF-kappa;B的基础研究极大地推动了对炎症、细胞凋亡及新生血管形成等相关疾病的认识,为相关疾病的发病机制和治疗研究开辟了新的途径。

睫状体位于虹膜后,是常规眼科方法检查的ldquo;盲区rdquo;,由于它的隐蔽位置,使睫状体及其相关
疾病的临床检查和诊断十分困难。超声生物显微镜检查(ultrasound biomicroscopy,UBM)采用高频超声波作为检测能源,可穿过透明组织和非透明组织。因此,UBM不但能观察到虹膜表面的形态,还能观察到后房及虹膜后组织的情况,其令人满意的分辨力和清晰度,为临床检查睫状体的形态、位置以及病变提供了良好的工具。现对UBM在睫状体及其相关疾病检查中的应用及其临床意义作一综述。(中华眼底病杂志,2002,18:79-81)

近年由于人类的忽视以及免疫抑制剂的广泛应用,结核感染呈现倍增趋势。结核菌感染可以累及全身各个系统,除晶状体外的眼部组织都可感染结核。脉络膜是眼部结核感染的好发部位。对于出现眼内团块的患者,特别是有免疫缺陷的高危人群,在诊断时应考虑结核感染。(中华眼底病杂志,2002,18:164-165)
