Chapter 122 is the beginning of the year

"Whether it works or not depends on the curative effect. Pen %fun %Pavilion www.biquge.info Hahaha, I can't help you then." Let's go, stop scratching your head. Meng Zhijing pushed the bull's eye burning and stared at his Gong Nian Huai, "I'm home, don't go in quickly." ”

Gong Nian Huai squinted at Meng Zhijing, "Brother Meng, it's okay, how to use the medicine must listen to the younger brother, otherwise, the little brother will," Gong Nian Huai is really not at ease.

In later generations, before penicillin was used, a skin test was done because some people were allergic to penicillin. If the allergic person is injected with penicillin, the consequences are extremely serious, ranging from rash, asthma and fever to shock and even death. In some people, just having a skin test can cause shock.

It is a matter of one's own credibility and the safety of patients' lives, how can the public lose Nianhuai to let others interfere casually. This is not the same thing as the side effects of ordinary Chinese medicine, and it is not clear to Meng Zhijing, and it is estimated that Meng Zhijing does not understand what allergies are all about.

In fact, the substance that causes allergies is not penicillin itself, but the polymer impurities in it. The content of these impurities varies with the manufacturer, production process and batch number, so it can be seen that even if a patient who has been injected with penicillin for a long time has to do a new skin test if he changes to a different batch of penicillin.

And the current production process, compared with later generations, is very different. The finished product of penicillin produced will inevitably have no less polymer impurities than the products of later generations. The safety of penicillin has always been a string that the public loses in his heart, and he does not dare to relax a little.

"What are you doing?" Meng Zhijing looked at Gong Nian Huai with a smile, he rarely saw Gong Nian Huai in a hurry, now that he has a chance, how can he let it go gently, watching a play is easier than acting.

Gong Yi stomped his feet and said hatefully, "The little brother has met a soldier, hmph, it's not in vain to say it, you don't understand it anyway, and you won't think about complying with it." The younger brother should save it. As he spoke, Gong Nianhuai put his hands behind his back and walked leisurely towards the door.

This poked Meng Zhijing's lung tube. was accused in front of him and said that he didn't understand, this face was beaten, the goods were sold for a skin, and the person lived with a face, and Meng Zhijing was also a young man with strong blood, a few years older than Gong Nian Huai, and was pointed at his nose and sprayed his face by Gong Nian Huai, this is contempt, or the kind of Chi Guoguo.

"Stop, you make it clear, what will you do?" Meng Zhijing blushed, walked a few steps, caught up with Gong Nian Huai, and reached out to grab Gong Nian Huai's clothes.

Gong Yi Nianhuai also seems to have a rear-view function, his body let go slightly, dodged the claws of Meng Zhijing from behind, raised his legs lightly, crossed the threshold, and then accelerated forward, and said the next sentence, "Little brother won't do it, see how you get the magic medicine." ”

"Oh, flirtatious." Meng Zhijing slowed down, put his hands behind his back, and also learned to cross the threshold leisurely, and the two of them floated into the yard like two dog-tail flowers one after the other, "That's great, the little brother is not a fledgling blue-headed boy, I and Zhang Yan are all covered." ”

Gong Nian Huai didn't believe it, laughed, kept under his feet, walked through the corridor, and went straight to the backyard.

"Stop for me, you still know how to come back." A person stepped out of the main room, under the scorching sun, his face was covered with frost, and stopped in front of Gong Yi Nian Huai and Meng Zhijing.

"Ahh Uncle Fang! Gong Nian Huai screamed, stopped his steps, held his breath, and stood obediently in place, not daring to move.

"Humph!" Fang Qiong's nose snorted lightly, his gaze swept over Gong Yi Nianhuai, and finally landed on Meng Zhijing's face.

"Qingyuan, your boss is not small, why don't you let people worry, look, the sun is past noon, I don't know how much work is waiting to be done in the backyard, so I don't say hello, run out and don't see anyone in the morning?"

"Uncle Fang, I'm ......" Meng Zhijing secretly glanced at Gong Yi Nianhuai, and gagged his mouth, wanting to distinguish.

"Okay, no amount of reasons can argue the facts." Fang Qiong sighed lightly, shook her head, and slowly walked towards the backyard.

The two glanced at each other and followed behind Fang Qiong, as docile as two puppies.

"Everything is ready, just wait for the two of you to come back and get to work." Fang Qiong said as she walked, "The general was so busy that he hit the back of his head in order to meet the stone judgment, you two, alas, are not sensible. ”

Where did the two dare to answer, they silently followed behind Fang Qiong, following in unison.

In the backyard, Zhang Yan sat on the horse and leaned against the wall to nap, and the elder grew down the corner of his mouth. Gong Nian Huai looked around, and laughed secretly, if there was a dog in the yard, would he come to Tian Ha Lazi. Thinking about it, Gong Nian Huai couldn't help but laugh out loud.

"Huh?" Fang Qiong's ears were very sharp, and she turned her head and glared at Gong Yi Nianhuai, "You kid is not convinced, right?" ”

"No, hehe, Uncle Fang, look at Brother Zhang," Gong Nian Huai stretched out his hand and pointed at Zhang Yan, "Brother Zhang is so cute in his sleep." ”

"Go, talking nonsense again, what's cute or not in your sleep, stupid." Fang Qiong followed Gong Nianhuai's fingers and looked at Zhang Yan, the corners of her mouth trembled, and she quickly pursed her lips again.

Meng Zhijing looked around, "Uncle Fang, just the four of us?" ”

"Hey, Qingyuan, do you still need to find a helper for this little work? Can you also find a helper to make miracle medicine? I look at you, why are you pumping more and more when you get bigger? Fang Qiong was originally walking well, but as soon as he heard Meng Zhijing's words, Huo Ran stopped, turned around, and glanced at Meng Zhijing up and down, his eyes full of light and shadow of heartache and hatred of iron and steel.

"Uncle Fang, I'm ......" Meng Zhijing's face was red and white, and he rolled his eyes when he was choked by Fang Qiong's words.

"Why don't you do it, the old man is not the same, you are crying out." Fang Qiong almost poked his finger into Meng Zhijing's forehead.

"Hehe, Uncle Fang, Uncle Fang, doesn't Brother Meng want to make the magic medicine quickly, besides, you are always an idle person, Brother Meng is worried that you are too hard." Gong Nian Huai hurriedly played the round, since the morning of the fight, Fang Qiong was like eating gunpowder, seeing who collapsed whom, he didn't agree with each other, and pulled out his gun to face each other. I don't know what stimulated Fang Qiong.

After this noise, Zhang Yan also opened his eyes, and saw that the three people in the yard, like fighting cocks, hurriedly stood up.

"The two sons are back!" Zhang Yan saw that Fang Qiong's expression was not good, he didn't dare to move his nest when he stood still, and shook his head at Meng Zhijing, not knowing what information to pass to Meng Zhijing, anyway, Gong Nian Huai didn't understand.

"Hehe, Brother Zhang, let's start refining the magic medicine." Gong Nian Huai ran to a few large wooden barrels, estimated to contain either vegetable oil or distilled water, and there were several wicker baskets next to them, which contained charcoal boiled in distilled water. These are all items that are necessary for the purification of penicillin.

Moving is an excellent medicine for releasing bad emotions. Quickly divert Fang Qiong's attention and ask the old man not to focus on grabbing other people's pigtails, and the whole atmosphere will be harmonious.

Therefore, Gong Nian Huai is like a marquee, wearing flowers and butterflies between jars and barrels, directing Meng Zhijing and Zhang Yan to move here and there, his body does not stop, and his mouth is not idle.

The day before yesterday, Meng Zhijing and Zhang Yan rehearsed the process of purifying penicillin, and now it is like a smooth process, without the slightest sense of rustiness.

It seems that the two of them are really interested in purifying penicillin, and they have gone through each step in their brains many times before they can do it as handy as they are now.

The three of them worked together to ignore Fang Qiong directly. No, it should be said that the three of them did the work they could do quickly and well, and Fang Qiong couldn't get involved at all. Besides, Fang Qiong didn't know the process, and it was not good to bend down and ask the three young people for advice, and soon, Fang Qiong became a marginal person, and could only wander around like an overseer.

When cultivating green mold, the concentration of the culture medium is different, and it is divided into three categories. The purification was also divided into three groups, and Fang Qiong happened to have prepared three large wooden barrels, which made the first step of purification orderly and orderly.

The three large wooden barrels are big enough, and the jars of green mold liquid in the yard look quite a lot, but the capacity cannot be compared with the wooden barrels, so a rough estimate can only digest the green mold in the jar in two rounds, and it seems that the workload is not very large.

Not really. A complete process should be divided into several links, each link is a multiple of the green mold solution, and several links are several multiples.

The first step is to filter the culture liquid with a funnel, and the second step is to pour the filtered culture liquid into the wooden barrel, and at the same time pour the vegetable oil into it, and stir well, the liquid is divided into three layers, just take out the bottom layer. So the bottom of the barrel was fitted with something similar to a later faucet, so that the liquid from the bottom could flow out. These liquids are solutions that contain penicillin.

The next step is to remove the impurities. This is where charcoal comes in handy.

The charcoal has been boiled in distilled water, detoxified, and ground to a fine powder that can now be thrown directly into the penicillin solution. Gong Nian Huai acted as a stirr, stirring constantly until the charcoal was full of penicillin. Due to the lack of measuring equipment, it is only a matter of feeling.

Pour out the residual liquid, and then wash the charcoal particles with distilled water to wash off the debris.

Finally, wash the charcoal pellets with vinegar water. Since penicillin is a weakly acidic substance, the alkaline substance can be washed away with acidic water containing vinegar. Alkaline water is then made from baking soda, and penicillin is dissolved from the charcoal into the water, and a high-purity penicillin solution can be obtained.

Can such a solution be used to cure diseases?

Theoretically, yes, but in practice no. There are still polymer impurities in the penicillin solution, which is also the cause of penicillin allergy in some people.

In order to be foolproof, Gong Nian Huai thought of a lot of ways, and finally came up with a solution.

This method is actually very simple, and there is only one tool needed, which is rice paper.

First of all, the solution is prepared first, and eight parts of acid and two parts of alkali are mixed together to make an acid-base solution; Then, cut the rice paper into long strips and apply penicillin solution to the ends to allow them to dry naturally, and finally lift the front end of the paper strip and immerse the end in an acid-base solution.

After the paper strip is inserted, the solution will rise along the paper strip due to the principle of capillary phenomenon.
