Skin lesions due to Okra (Hibiscus esculentus L.): proteolytic activity and allergenicity of Okra.
Contact dermatitis, 1992Co-Authors: Fumi Manda, K Tadera, Kohji AoyamaAbstract:The present report describes experimental studies on the proteolytic activity of the secretion on the surface of Okra pods and the allergenicity of Okra components, to clarify the etiology of skin lesions due to Okra. Proteolytic activity was detected on the surface of immature Okra pods and seemed to be sufficient to cause the skin lesions. Further, in vivo, intradermal injection of the enzyme solution prepared from immature Okra pods led to increased capillary permeability in guinea pigs, in contrast to heated preparations. The fraction purified by preparative paper chromatography from an ethyl acetate extract of Okra pods showed moderate allergenicity in the guinea pig maximization test. The present experimental evidence supports our suggestions from previous surveys that the proteolytic enzyme of Okra may be responsible for development of skin lesions, and that allergic contact dermatitis may also play a part in addition to irritant contact dermatitis.

Skin lesions due to Okra(Hibiscus esculentus L.). A field survey of skin lesions in workers cultivating Okra.
JOURNAL OF THE JAPANESE ASSOCIATION OF RURAL MEDICINE, 1991Co-Authors: Fumi MandaAbstract:The outbreak of skin lesions in workers cultivating Okra (Hibiscus esculentus L.) was studied by a field survey. Questionnaire and physical examinations including patch tests with preparations of Okra pods were carried out.Out of 89 workers, 48 (53.9%) reported to have history of skin lesions. The sites of skin lesions were mainly arms (43.8%), dorsal regions of hands (35.4%), neck (33.3%), fingers and fingertips (each 29.2%). Concerning the symptoms of the skin lesions, itching (85.4%) and flare (45.8%) were dominant on picking work, and vanishing fingerprints and fissures on fingers on packing work. These clinical signs appeared shortly after the workers set to work without protective means.Positive reactions of the patch tests with preparations of Okra pods were found in 11 out of 89 Okra workers (12.4%). The positive rate in non-Okra workers was 3.4%. The results indicated that skin lesions due to Okra were caused by primary irritation and allergic sensitization.

APLIKASI BEBERAPA DOSIS TRICHOKOMPOS ECENG GONDOK TERHADAP PERTUMBUHAN DAN HASIL TANAMAN Okra (Abelmoschus esculentus l. Moench)
2019Co-Authors: Afwi Zusicho - PratamaAbstract:TERHADAP PERTUMBUHAN DAN HASIL TANAMAN Okra (Abelmoschus esculentus l. Moench) Afwi Zusicho Pratama (11482102607) Di bawah bimbingan Novita Hera dan Oksana INTISARI Okra merupakan tanaman yang memiliki kandungan gizi tinggi. Beberapa di negara tropis, Okra belum dapat dicapai hasil produksi yang optimum dan kualitas yang tinggi, karena terus menurunnya kesuburan tanah. Salah satu cara untuk meningkatkan kesuburan tanah dan produksi tanaman Okra adalah dengan pemupukan pupuk trichokompos eceng gondok. Penelitian ini bertujuan untuk mengetahui dosis terbaik trichokompos eceng gondok terhadap pertumbuhan dan hasil tanaman Okra. Penelitian ini telah dilaksanakan di Laboratorium Agronomi dan Lahan percobaan Fakultas Pertanian dan Peternakan Universitas Islam Negeri Sultan Syarif Kasim Riau pada bulan Februari sampai April 2019. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan perlakuan pemberian pupuk trichokompos eceng gondok terdiri dari 7 taraf kontrol, 80 g/polybag, 160 g/polybag, 240 g/polybag, 320 g/polybag, 400 g/polybag, 480 g/polybag. Parameter yang diamati adalah tinggi tanaman, jumlah daun, diameter batang, jumlah buah, bobot buah perbuah, bobot buah pertanaman, panjang buah, diameter buah. Hasil penelitian ini menunjukkan bahwa perlakuan dosis trichokompos eceng gondok dari 0 – 480 g/polibag mengahasilkan pertumbuhan dan hasil tanaman Okra yang sama. Kata kunci : Okra, pupuk trichokompos, eceng gondo

Pengaruh Ketebalan Mulsa Jerami Terhadap Pertumbuhan dan Hasil Tanaman Okra (Abelmoschus esculentus L. Moench)
'Orissa Journal of Otolaryngology and Head and Neck Surgery', 2020Co-Authors: Monica Silva, Baskara Medha, Herlina NinukAbstract:Tanaman Okra (Abelmoschus esculentus L. Moench) merupakan tanaman yang kaya akan manfaat dan multifungsi, Tanaman Okra merupakan tanaman yang kaya akan manfaat karena memiliki kandungan lemak, protein, karbohidrat, mineral, dan vitamin. Dilihat dari potensi tersebut maka Indonesia memiliki peluang besar menjadi pengekspor Okra, untuk itu diperlukan upaya peningkatan hasil tanaman Okra di Indonesia. Okra merupakan tanaman yang membutuhkan cukup banyak air. Salah satu upaya yang dapat dilakukan untuk meminimalisir tingkat kehilangan air dapat dilakukan dengan upaya modifikasi kondisi lingkungan tumbuh dengan cara rekayasa lingkungan dengan cara aplikasi mulsa organik untuk meningkatkan pertumbuhan dan hasil tanaman Okra secara maksimal. Penelitian dilaksanakan pada bulan Maret hingga Juli 2019 di Desa Kepuharjo, Kecamatan Karangploso, kabupaten Malang, Provinsi Jawa Timur. Hasil penelitian menunjukkan pemberian mulsa jerami dengan berbagai ketebalan menunjukkan pengaruh terhadap komponen pertumbuhan seperti jumlah daun, dan luas daun. Pada komponen hasil memberikan pengaruh pada jumlah polong, bobot segar polong per tanaman, bobot segar polong per petak, dan bobot polong per ha. Tanaman Okra yang diberi mulsa jerami dengan ketebalan 7,5 cm menghasilkan polong per hektar yang tertinggi, yaitu sebesar 10,24 ton ha-1
