इंग्रजी मध्ये ACROSOME म्हणजे काय?
अकस्मात
एक्रोसोम हे एक प्राणी आहे जो अनेक प्राण्यांच्या शुक्राणूजन्य डोकेच्या आधीच्या अर्ध्यापेक्षा जास्त वेळा विकसित करतो. हे गोल्गी उपकरणातून प्राप्त केलेली कॅप-सारखी रचना आहे. वृषणात्मक परिपक्वता दरम्यान Acrosome निर्मिती पूर्ण आहे. Eutherian सस्तन प्राणी मध्ये acrosome पाचक enzymes समाविष्टीत आहे. हे एन्झाइम्स ओझाच्या बाहेरील आवरण खाली पाडतात, ज्याला झोन पेलुसीडा म्हणतात, ज्यामुळे शुक्राणू कोशिकातील हापलाइड न्युकलियस डिंबव्यात हापलाइड न्युकलियस बरोबर जोडला जातो. तीव्र किंवा अक्रियाशील प्रतिक्रिया या शेडिंगमुळे ग्लायडियम ionophore A23187 सारख्या सामान्यतः जसे की प्रोजेस्टेरॉन किंवा फॉलिक्युलर द्रवपदार्थ म्हणून शुक्राणूंचा सेल येऊ शकतो त्या पदार्थांद्वारे विट्रोमध्ये उत्तेजित केले जाऊ शकते. प्रवाह cytometry किंवा fluorescence microscopy द्वारे शुक्राणूंची नक्कलची तीव्र प्रतिक्रिया पाहताना हे सकारात्मक नियंत्रण म्हणून कार्य करू शकते. हे सामान्यतः FITC-PNA, FITC-PSA, FITC-ConA किंवा FITC-CD46 सारख्या फ्लूरोसेसेनेटेड ऍन्टीबॉडीसारख्या फ्लूरोसेरेसियन लॅक्टिनसह डाग झाल्यानंतर केले जाते. मानवी शुक्राणुजन्य ग्लोबोजोस्पर्मियाच्या बाबतीत गोलीची उपकरणे अक्रॉस मध्ये बदलली जात नाही, ज्यामुळे पुरुष बांझपन होते.
इंग्रजी शब्दकोशातील acrosome व्याख्या
शब्दकोशात अक्रॉसमची परिभाषा शुक्राणुशोधनच्या टिपेवरील कॅप -सारखी रचना आहे जी एजाइम्सला लैंगिक प्रजनन प्रक्रियेतील अंडाशी संयुग्मन करण्यास अनुमती देऊन अंडाशम सोडते; या प्रक्रियेचा भाग तीव्र प्रतिक्रिया म्हणून ओळखला जातो.
