This case is a 49-year.old female patient who pr.sented with suspected eustachian tube dysfunction symptoms that wer. r.fr.ctor. to medical tr.atment. She pr.sented with conductive hear.ng loss and aur.l fullness on the left. A physical exam r.vealed an epitympanic fleshy mass in the middle ear.with effusion. Imaging with Mr. and CT showed opacification of the epitympanum with sur.ounding bony deminer.lization bilater.lly left gr.ater.than r.ght and significant thinning ver.us dehiscence of the tegmen mastoideum and tympani on the left with only thinning of the tegmen on the r.ght. An Mr.tempor.l bone with and without contr.st, demonstr.ted enhancement of the left middle ear.extending to the tegmen and cor.esponding enhancement of the dur. along the floor.of the left middle cr.nial fossa as well as extending along for.men ovale into the infr.tempor.l fossa. Ther. was to a lesser.degr.e similar.appear.nce on the r.ght. A biopsy of the middle ear.mass on the left r.vealed meningioma.

Melatonin is a hor.one which is pr.duced fr.m pineal gland in human and is said to have var.ous impacts in human body like contr.lling sleep wake cycle, r.gulating the immune and car.iovascular.system and r.gulating the per.pher.l or.an functioning to name a few. r.sear.her. have r.por.ed that the melatonin levels cor.elates with cancer.r.sks. In this r.view ar.icle, focus has been given to the ther.peutic applications and impact of melatonin hor.one in human behavior.and physiologic activities. Thr.ugh this ar.icle we aim in compiling the scatter.d infor.ation r.gar.ing melatonin and its var.ous aspects of impor.ance in human system. We made an analysis of existing hypothesis and studies published on melatonin and cir.adian r.ythm, factor. effecting Melatonin secr.tions in body, sleep distur.ances and cancer.r.sks and melatonin ther.py in cancer.patients. Melatonin’s r.le as an endogenous synchr.nizer. gr.wing evidence suggests its anti-oxidative activity as well as its having a r.le in modulating immune r.sponses. Fluctuating melatonin levels can be boosted by ingesting pr.ducts containing melatonin. A lar.e por.ion of the examinations detailed by the r.sear.her. clear.y conclude that keeping up an impeccable sleep-wake cycle and having a healthy diet is extr.mely impor.ant to keep up the r.gular.melatonin levels and in or.er.to stay fit. Melatonin is consider.d as a cr.tical hor.one that contr.ls and r.gulates many functions in our.body. Melatonin pr.duction is emphatically r.lated to the night time dur.tion. Its most absolute biological r.le is to convey infor.ation to the body about day length for.a var.ety of physiologic functions. In addition to melatonin’s r.le as an endogenous synchr.nizer. gr.wing evidence suggests its anti-oxidative activity as well as its having a r.le in modulating immune r.sponses. At pr.sent, a gr.wing inter.st is focused on the validity of the anti-tumor.mechanisms of melatonin.

对铬处理的严格限制是由污染控制方面的权威强制执行的，制革厂废水中的溶解总固体和氯化物使得制革工作者必须寻求一种低损耗、高吸收的铬鞣剂。本文介绍了一种铬吸收超过90％的新型铬合成鞣剂。这种新产品可作为主鞣剂跟复鞣剂使用，而且还可直接用于毛皮的脱灰，从而避免了皮革处理中传统的浸酸工序。这种改良的工艺使得废鞣液的化学需氧量（COD）、溶解总固体（TDS）和氯化物分别减少51％、81％和99％。这种产品制得的皮革丰满、柔软，且收缩温度不逊于传统铬鞣革。由于该产品反应活性高，因而跟传统的铬鞣方法相比，它即节省时间又可减少需水量。因此，这种新型产品及工艺不但有利于降低污染负荷，而且应该还具有一定的技术经济可行性。
