Description

种抗艾滋病的中药煎赍及其制备方法 发明的技术领域
中药抗艾滋病育滋, 又名 "中药生命泉" 及其制法, 属于由植物材料构成 的中药抗艾滋病医用配制品技术领域。
发明的技术背景
目前, 艾滋病已波及全球 1 60多个国家和地区. 在亚洲呈明显上升趋 势。艾滋病是由于 H I V感染所引起的以细胞免疫缺陷为主要表现的自身免疫 性疾病, 其治疗包括: 对抗以 H I V为主的病毒感染和其他条件性病原体感 染、调节免疫机能、治疗恶性病变 (如卡波氏肉瘤、淋巴瘤) 和支持疗法。据 悉目前美国正在研制幵发抗艾滋病的新药不少于 50种, 但是经 FD A批准用 于临床的仅只有叠氮胸苷 ( A Z T ) 、 双脱氧肌苷 (D D I ) 、 双脱氧胸苷 (DDT) 、双脱氧胞苷 (DDC)等. 但是这些药物不能根治艾滋病, 副作 用大, 价格昂贵。 正如在 1993年夏, 于柏林召幵的国际艾滋病大会上有学 者通过长期研究认为. 虽然叠氮胸苷 (AZT) 能暂吋缓解艾滋病的症状, 但 由于很快产生耐药性和明显的骨髓抑制毒性, 故不能延长 H I V感染者和艾滋 病人的生命。鉴此, 近十几年以来, 我国不少学者对中草药和中药复方制剂进 行了免疫病理研究。就其对免疫功能的影响的分类和临床试用效果方面^ — 定的成效。 中草药及其复方制剂的药理作用体现在以下方面: 对抗病毒和某些 机会性感染, 提髙或抑制机体的免疫机能和对免疫机能的影响以及双向调节机 理。 当今, 国内外常用于治疗艾滋病的中药有: 甘草甜素 (即强力宁) 、八味 黄芪片、香茹多糖等。据报道这些中药有抑制艾滋病毒的形成和感染细胞的变 性的作用, 对某些艾滋病症有一定疗效。 从专利文献检索获悉: 在本发明申请 专利之前, 已经有相近的以中药为原料治疗艾滋病的各种中药制剂向中国专利 局提出申请, 例如 《中成药艾滋灵制剂的生产方法》 [CN 8810004 8 A ( 1988 ) 〗; 《防治艾滋病中药方剂的制备方法》 [ C N 1062844 A ( 1992 ) ]; 《一种治疗艾滋病的药物》 [CN 1092661 A ( 19 94 ) ]; 《中草药抗艾滋病制剂》 [CN 1 091 64 1 A ( 1 99'4 ) ] 等。从上述文献所公开的内容可知, 它们系一种抗病毒、增强免疫力和对症治 疗的制剂; 制备方法简单; 服用方便;无明显毒副反应: 且经临床小量试验; 具有抗艾滋病的作用。将本发明技术方案与上述的文件对比可知, 它们的技术 方案不相同. 且本发明的技术方案经过动物试验和临床试验的检验, 从而证明 了中药抗艾滋病青滋设计方案的可行性和有效性。
发明的主要内容
本发明的目的在于: 为艾滋病患者提供一种疗效高、副作用小、安全可 靠、价格较便宜的中药制剂。
中药抗艾滋病資滋所需给予保护的技术方案如下: 本发明技术方案的基本 设计思想是选择促使 C D 4 和 C D 8 淋巴细胞上升; 对免疫机能有双向调节 作用; 能抗炎、抗病毒和改善机体营养状况的中草药为原料组份. 并根据临床 试用, 研究分析拟定出相应的组份比例及其生产制备工艺流程。按此组份和重 量比例以及工艺流程配制, 即可制备出中药抗艾滋病育滋。
中药抗艾滋病育滋的组份和重量比例如下: 党参 1 2份、 白术 1 2份、茯 苓 1 2份、炙甘草 6份、黄芪 1 0份、熟地 1 0份、 当归 6份、 白芍 9份、阿 胶 10份、杜仲 1 0份、续断 10份、 山茱萸 9份、枸杞 10份、覆盆子 1 0 份、泽泻 9份、吐温 -801 2份、苯甲酸钠 2份、冰糖 330份。
中药抗艾滋病育滋按以下次序的步骤方法进行制备。
(1 )取党参 1 2份和重量为党参 10倍的 60%的乙醇作溶媒, 使用常 规的渗漉法进行操作。 即将党参置于乙醇中浸渍 24小时后, 再行渗漉, 弃药 渣; 回收乙醇; 提取党参中的有效成份, 并使其浓缩为稠膏. 相对密度为 1.3, 备用。 因为党参中的皂甙、微量元素和氨基酸等有效成份. 既可用 6 0 %乙醇作为溶媒提取又能降低淀粉等杂质的溶出量。
( 2 ) 取阿胶 1 0份. 对其加温至 60°C- 8 0°C, 使之溶化均匀, 备 用。
(3 )取白术 1 2份、 当归 6份、 白芍 9份、泽泻 9份、覆盆子 1 0份, 将它们混合之后, 在 1 00°C-1 20°C的环境下蒸馏 6小时, 提取它们的挥 发油, 实验证明可以提取恽发油总量的 98 %, 再将余下的药渣与水相混合, 在 100°C的环境下煎煮 2小时, 经过滤, 弃药渣, 取药液, 再将药液与挥发 油混合 备用。
(4 )取熟地 1 0份、 山茱萸 9份、杜仲 1 0份、茯苓 12份、续断 1 0 份、炙甘草 6份、黄芪 1 0份、枸杞 10份。将它们切成 2-3寸长, 以 3-5 目为宜, 用清水洗净, 捞起沥干后. 置于锅中, 加水, 使水面高于药材面 2- 3寸, 上压竹匾. 煮至沸腾. 在维持沸腾状态下, 共煎煮三次, 每次 1小时, 且每次均经过滤, 弃药渣, 取药液. 并将三部份药液合并. 浓縮至稠育状. 使 其相对密度为 1.3. 备用。实验证明. 上述的每次煎煮时间和提取次数是较 合理的。
(5 ) 将浓缩的党参稠青, 溶化均匀的阿胶、 白术、 当归、 白芍、泽泻、 覆盆子的恽发油与药液的混合物, 熟地、 山茱萸、 杜仲、茯苓、 续断、 炙甘 草、黄芪、枸杞的混合稠 ¾P进行混合. 使之均匀。
( 6 )取冰糖 330份, 加温使之均匀溶化, 备用。
( 7) 将党参等 1 5味药构成的稠音与溶化均匀的冰糖混合, 在 60 C - 80 °C的环境下再进行 30分钟的加温处理。
(8 ) 在党参等 1 5味药与冰糖合成的育滋出锅之前 1 5分钟的时刻, 加 入苯甲酸钠 2份, 吐温- 801 2份, 其中吐温 -80以 1.2g/ral的状态加入. 将 它们混合、收 ¾f, 即成为中药抗艾滋病育滋。 其相对密度为 1.3。经筛选实 验结果证明. 选用 2份的苯甲酸钠和吐温 -801 2份作为防腐剂和增溶剂是适 宜的。
此外, 中药抗艾滋病資滋应按照企业技术标准进行检测。
根据上述工艺过程, 即可绘制出工艺流程图. 如说明书附图所示。
中药抗艾滋病膏滋的技术要求如下 ·.
( 1 ) 感官要求: 棕褐色, 香甜、微酸. 粘稠适中. 细腻. 无肉眼可见的 杂质和口感无砂。
( 2 )理化指标 '·

致病菌 不得检出 按照上述技术方案设计、制备的中药抗艾滋病 滋就是本发明的一种最好实施 例。
为了验证本发明所设计的技术方案的可行性和有效性以及它与现有治疗艾 滋病的药物相比所具有的有益效果. 发明人在有关科研、教学单位协作下. 曾 进行了多项实验研究, 现将这些研究项目内容及其结果简述如下:
( 1 ) 中药抗艾滋病膏滋对 H I V— I ( I型人类免疫缺陷病毒. 即 I型 艾滋病毒) 、 H I v— ll (Π型人类免疫缺陷病毒. 即 II型艾滋病毒) 抑制作 用的研究。其结果证明: 中药抗艾滋病脊滋在体外细胞内对 H I V- I有轻度 抑制作用, 对 H I V— II有明显抑制作用。
( 2 ) 中药抗艾滋病育滋最低抑菌浓度 (M I C ) 的实验研究。研究结果 证明, 该药物对白色葡萄球菌、链球菌、痢疾杆菌和伤寒扦菌均有抑制作用。
( 3 ) 中药抗艾滋病膏滋对小鼠免疫功能影响的实验研究。 受试动物是 6— 8周齡. 体重为 1 8— 22g, 雌雄各半的小鼠. 随机分为三组. 其中两 组为对照组, 一组为实验组。 实验证明:当服用中药抗艾滋病青滋后, 可以增 强小鼠非特异性免疫机能及细胞免疫、血液免疫功能。
(4 ) 中药抗艾滋病 滋急性毒性实验研究。受试动物是体重 18— 22 g小鼠 4 0只, 雌雄各半分为两组, MTD为 1 2 Og/kg. 相当于人临床用量 (1. 2 g/k g ) 的 100倍。观察 7天之后, 两组无一只死亡. 且外观、 行为、活动、摄食等无异常, 未得出 L D 50 , 从而证明急性毒性试验无毒。
( 5 ) 中药抗艾滋病青滋长期毒性试验。受试动物是 S D大白鼠. 6— 7 - 周龄, 体重 80 ± 1 5g, 雌雄各半. 毎组 7 7只, 设实验组和对照组。给实 验组口服大剂量 (分 3. 75m 1/k g , 6. 5m 1/k g■ 1 3m 1/k 9三种不同剂量进行, 为临床剂量的 2 7倍) 的情况下, 经 1 80天口服毒性 试验, 发现受试动物的体重增长较对照组迟缓、 fl卑脏轻度瘀血; 高剂量组的少 数大 S鼠的心肌纤维萎縮和少数心肌纤维空泡变性。但停药 4周后即可以恢复 正常。 从而说明中药抗艾滋病資滋无明显毒性. 按规定的剂量和疗程使用是安 全的。
( 6 ) 中药抗艾滋病胥滋对大鼠垂体一一肾上腺皮质轴作用的实验研究。 受试动物是 Wistar大鼠 50只, 雌雄各半, 体重 1 20 ± 30 g, 中药抗艾滋 病育滋为 2 g/ml 试验证明本药物对大鼠垂体一一肾上腺皮质轴无兴奋和抑制 作用。
在动物实验的基础上进行了临床试验研究。 发明人曾使用本育滋对艾滋病和艾滋病相关综合症患者 2 7例进行治疗, 其中中国籍患者 2 0人, 外国 (缅甸、 泰国) 籍患者 7人. 包括了四个民族。 历时 3个月, 后又跟踪随访一年。治疗结果如下: 经治疗症状和体征得到明显 的改善. 体温恢复正常. 腹泻停止, 皮疹消散或明显减少,机会性感染少、体 重增加、实验指标得到不同程度的改善。在 2 7病例中, 显效者 1 8例 (占 6 6.7%) , 有效者 8例 (占 2 9. 6%) , 一度无效, 病情有反复又未坚持 治疗而死亡者 1例 (占 3 · 7%〉 。
以上实践证明: 中药抗艾滋病育滋与现行巿场上所销售的同类药物相比 较, 前者对艾滋病的治疗效果是明显的或比较明显的; 且无副作用; 安全可 靠;价格便宜, 以一个疗程计算. 其价格仅为西药的二十分之一。
