Subsequently, post World War-I was a period of intensive work in maintaining such ethnobotanical records, in which the use of quinine has remained the drug of choice in malaria. After World War-II new chemical techniques were used to fractionate and isolate, and also for structure determinations, which led to an ever increasing number of potential antiplasmodial compounds. Recently experimental studies in animals and in clinical trials, showed the emergence of CQ-sensitive and CQ-resistant strains of Plasmodium. This paper is an attempt to update a historical list of antimalarial plants and their natural products as studied by pharmacognostic extraction methods of crude drug research of those times. Further an attempt has been undertaken to list the compounds as classified into three major groups, namely alkaloids, terpenes and quassinoids and aromatic and miscellaneous compounds. The most promising is a quassinoid, artemisinin derived from Artemisia annua which has caused a resurgence for the quest of newer antimalarial compounds.</p>","PeriodicalId":77174,"journal":{"name":"Indian journal of malariology","volume":"35 2","pages":"57-110"},"PeriodicalIF":0.0,"publicationDate":"1998-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21313554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was observed that malaria had been changing its clinical profile. The classic paroxysm is evident only in 40% cases of P. falciparum and 47.27% of P. vivax malaria, but the difference between the two groups is not statistically significant. On the other hand continuous or remittent type of fever has been observed in 40% and 27.27% cases of P. falciparum and P. vivax respectively, while absence of classic paroxysms of fever, in association with splenomegaly when present, poses a diagnostic difficulty with enteric fever. Association of jaundice in 40% and 9.09% cases with P. falciparum and P. vivax respectively along with hepatomegaly in 80% and 63.63% in them in conjunction with nausea and/or vomiting leads to clinical mimicry with infective hepatitis. Splenomegaly which has been described as cardinal feature of malaria was observed in 40% cases with P. falciparum and only in 18.18% cases of P. vivax malaria and this is a clear deviation from earlier description and this difference between the two groups is highly significant at 99% level of confidence. Co-existent enteric fever was observed in 3.33% of falciparum and 2.6% of vivax malaria, though this difference is not statistically significant. Acute respiratory distress was observed in 6.6% of P. falciparum malaria only. Oliguria with impaired renal function was noted in 5% cases of P. falciparum malaria. The present study has also noted convulsion or coma in 8.33%, purpura with disseminated intravascular coagulation in 3.33% and black water fever in 3.33% cases in falciparum malaria which were not observed in cases with vivax malaria and these differences are statistically significant. However, stupor with bilateral extensor planter response was observed in two cases (1.3%) of vivax malaria.</p>","PeriodicalId":77174,"journal":{"name":"Indian journal of malariology","volume":"35 2","pages":"111-6"},"PeriodicalIF":0.0,"publicationDate":"1998-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21313555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
