Methods: Disease confirmation was done by ASS1 gene mutation analysis using Next Generation Sequencing, DNA Sanger sequencing and bioinformatics. The study group members were17 citrullinemia type1 patients from 10 unrelated families referred to Iranian National Society for the Study of Inborn Errors of Metabolism’s clinic between 2008-2020. Clinical, laboratory and molecular data were retrospectively evaluated. Results: Eleven different ASS1 gene mutations were detected. Presentation: 3/17 (76%) neonatal, 3/17 (18%) late infantile, 1/17(6%) asymptomatic. Severe developmental delay and intractable seizures despite metabolic control was the only surviver of neonatal form outcome. Two patients with late infantile form live metabolically and seizure controlled with quite normal performance. DNA mutations: 7 missense, 1 nonsense, and 2 indel mutations in twelve, two, three patients, respectively. Five novel mutations were detected including a homozygous GG deletion in exon 11 (c.790_791delGG; G264Pfs*3) and a homozygous mutation in exon 6 (c.440C>T; p.M147T), both leading to infantile form; a homozygous mutation in exon 14 (c.1130T>C; p.M377T) leading to neonatal form; two compound heterozygote mutations in exon 14 (c.1167_1168insC& c.1186T>A; p.S396T) leading to asymptomatic form. Five patients (38%) with classic neonatal form had mutation in exon14 of ASS1 (c.1168G>A; p.G390R). Conclusions: Classic neonatal form was the most common form of disease in Iranian studied patients and exon 14: c.1168G>A; (p.G390R) was the most frequent ASS1 gene mutation. Global neonatal screening in Iran is recommended for citrullinemia type1 and certain mutations can be used for screening lethal form of disease in this population.","PeriodicalId":7277,"journal":{"name":"Advanced techniques in biology & medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74257306","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}

The wound healing potential of the ethanolic extractointment of Cocos nucifera(coconut) husk ash was evaluated in albino rats using excision wound model. Eighteen ratswere divided into three groups of six each. Group 1 received no treatment (blank ointment base) which is thenegative control, Group II received treatment with 1% silver sulphidiazine and group III received treatment withcoconut husk ash extract. 1% silver sulphidiazine ointment was used as standard for the activity comparison. Woundhealing was monitored on day 4, 8, 12 and 16. Wound healing parameters such as percentage of wound contractionrate and epithelialization period were observed. Studies on the antibacterial activity of crude ethanolic extract ofcoconut husk ash was conducted using agar well diffusion method and the minimum inhibitory concentration wasalso determined. The results showed that topical application of coconut husk ash extract incorporated into anointment base served to accelerate the wound healing process and specifically increased epithelialization in treatmentgroups compared to the other groups. The ethanolic extract of Cocos nucifera(coconut) husk ash inhibited growth ofall test organisms though it was dose dependent. The minimum inhibitory concentration values obtained for thecoconut husk ash extract against Escherichia coli,Staphylococcus aureus and Pseudomonas aeruginosa was 8 mg/ml,8 mg/ml and 10 mg/ml respectively. The results obtained shows that the Cocos nucifera (coconut) husk ash extract has a good wound healing and antibacterial activity and may be useful in managing wounds.","PeriodicalId":7277,"journal":{"name":"Advanced techniques in biology & medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88522638","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}
